UY_ALPHA-DISTRIBUTIONS_SWOOPS (spase://NASA/NumericalData/Ulysses/SWOOPS/AlphaParticle/FitParameters/PT4M)
Description
This file contains the distribution function of alpha particles. DATA REDUCTION:
The SWOOPS (Solar Wind Observations Over the Poles of the Sun) ion instrument is
a spherical-section curved-plate electrostatic analyzer. Particle arrival
directions are measured in spacecraft coordinates of azimuth (scanned by
spacecraft rotation) and elevation (determined by the detector number) angles.
The spacecraft spin axis was oriented toward the Earth. The energy/charge (E/q)
resolution was ~2.5% while the azimuth (phi) and elevation (theta) resolutions
were both ~5.6o. A description of the SWOOPS is given in a paper by S. J. Bame,
D. J. McComas, B. L. Barraclough, J. L. Phillips, K. J. Sofaly, J. C. Chavez, B.
E. Goldstein, and R. K. Sakurai, Astronomy and Astrophysics Supplement Series,
Ulysses Instruments Special Issue, Vol. 92, No. 2, p.237-265, 1992. The number
of counts in each E/q-phi-theta bin were examined to determine the peak of the
proton and alpha particle distribution, respectively, and the vector magnetic
field (in spacecraft coordinates) was obtained for the time at which the peak
was measured. A "coarse" 2-dimensional matrix was then formed by rotating the
data into a coordinate system with axes parallel and perpendicular to the field
direction. Note that gyrotropy is assumed in making that transformation. The
resolution of the matrix is "coarse" because the vector velocity assigned to
each bin was taken to be at the center of the bin. In reality, the counts in
each bin were probably not smoothly distributed in velocity space over the bin,
but were weighted toward the part of the bin nearest the center of the peak of
the velocity distribution. The "coarse" distribution would thus yield values for
the density and temperature that were higher than the true values. A correction
for that effect was accomplished by fitting contours to the coarse distribution,
breaking each bin or pixel into subpixels, and then using the contours and the
calibrated angular responses to distribute the counts among the subpixels. New
contours were then computed and the process was continued until it converged.
More details about this deconvolution of the angular data are given in the
appendix of a paper by Neugebauer, M., et al., "Ion distributions in large
magnetic holes in the fast solar wind", J. Geophys. Res.,106, 5635, 2001. This
procedure generated the matrix of velocity distribution functions of protons and
alpha-particles parallel and perpendicular to the simultaneously measured
magnetic field.

UY_ALPHA-FIT-PARAMETERS_SWOOPS (spase://NASA/NumericalData/Ulysses/SWOOPS/AlphaParticle/ParticleDistributions/PT4M)
Description
This file contains  the parameters obtained by fitting data to a bi-maxwellian
core-beam distribution. Under normal circumstances, the first (slow) population
is the core and the second (fast) population is the beam. When the
interplanetary magnetic field is folded back on itself due to turbulence or
other processes the relation of the first and second populations to the core and
beam, respectively, is reversed (see, e.g, M. Neugebauer and B. E. Goldstein,
AIP Conf. Proc. 1539, 46, 2013). The vector magnetic field is given in  RTN
coordinates and it was obtained for the time at which the peak of the alpha
distribution function was measured. Only good fits are retained.

UY_ALPHA-MOMENTS_SWOOPS (spase://NASA/NumericalData/Ulysses/SWOOPS/AlphaParticle/Moments/PT4M)
Description
This file contains the moments obtained from the distribution function of alpha
particles after deconvolution using the same magnetic field values used to
construct the matrices. The vector magnetic field and the particle velocity are
given in inertial RTN coordinates. The magnetic field was obtained for the time
at which the peak of the alpha distribution function was measured. The particle
velocity was obtained after rotating the fluid velocity from spacecraft to RTN
coordinates and taking into account the spacecraft velocity. During periods of
spacecraft nutation only the bulk speed and density are reliable, individual
velocity components and temperatures are invalid. The beginning of
scientifically useful SWOOPS data is at Day 322, 00:59 of 1990; at that time the
spacecraft was already nutating; nutation ceased as of Day 351, 22:00, 1990.
There are small systematic uncertainties in the velocity components. These are
due to such effects as uncertainty in the accuracy of alignment on the
spacecraft, relatively wide angular bins, variation in gains between
channeltrons, etc. The velocity component data should not be used for studies of
large scale, long term, solar wind deflection. The data are generally suitable
for all other studies.

UY_COHO1HR_MERGED_MAG_PLASMA (spase://NASA/NumericalData/Ulysses/MAGandPLS/PT1H)
Description
ULYSSES data have been reprocessed to ensure a uniformity of content and
coordinate systems relative to data from other deep-space missions:
- All spacecraft trajectory data were transformed to a Heliographic Inertial
(HGI) coordinate system.
- calculation of RTN Spherical components of the solar wind velocity from RTN
cartesian components:
- merging of trajectory coordinates, magnetic field data, proton fluxes, and
plasma data files into a single annual file ULY_YR.DAT, where YR is the year;
- Data gaps were filled with dummy numbers for the missing hours or entire days
to make all files of equal length.  The character \Ə\' is used to fill all
fields for missing data according to their format, e.g. \' 9999.9\' for a field
with the FORTRAN format F7.1. Note that format F7.1 below really means
(1X,F6.1),etc.
Note that an COHOWeb interface to this dataset, providing data subsetting and
and graphical browsing, is available at http://cohoweb.gsfc.nasa.gov/ 
The difference between T (Large) and T (Small) is discussed at
ftp://nssdcftp.gsfc.nasa.gov/spacecraft_data/ulysses/plasma/swoops/ion/swoops_io
n_users_guide_update_20030214.txt
The Heliographic Inertial (HGI) coordinates are Sun-centered and inertially
fixed with respect to an X-axis directed along the intersection line of the
ecliptic and solar equatorial  planes. The solar equator plane is inclined at
7.25 degrees from the ecliptic. This direction was towards ecliptic longitude of
74.36 degrees  on  1  January  1900  at  1200  UT; because of precession of the
celestial equator, this longitude increases by 1.4 degrees/century. The Z axis
is directed perpendicular and northward from the solar equator, and the Y-axis
completes the right-handed set. This system differs from the usual heliographic
coordinates (e.g. Carrington longitudes) which are fixed in the frame of the
rotating Sun.
The RTN system is fixed at a spacecraft (or the planet). The R axis is directed
radially away from the Sun, the T axis is the cross product of the solar
rotation axis and the R axis, and the N axis is the cross product of R and T. 
At zero Heliographic Latitude when the spacecraft is in the solar equatorial
plane the N and solar rotation axes are parallel.

UY_H0_GLG (spase://NASA/NumericalData/Ulysses/SWICS/GSFC/SPDF/PT13M)
Description
The Ulysses/SWICS instrument is a mass spectrometer combining an 
electrostatic analyzer with post acceleration, followed by a time-of-flight 
and energy measurement. The instrument covers an energy per charge range 
from 0.16 to 59.6 keV/e with a time resolution of about 13 minutes.
SWICS is designed to determine uniquely the elemental and ionic-charge 
composition, the temperatures and mean speeds of all major solar wind ions, 
from H through Fe. For more information see G. Gloeckler, J. Geiss et al., 
Astron. Astrophys. Suppl. Ser. 92, 267-289, 1992.
This archive consists of all 18 Matrix Rates (MR) as a function of energy 
per charge (E/q) and of time. Each MR represents a specific element in one 
or several ionization states, but it may also contain significant 
contributions from neighbouring elements due to spillover. The MRs are given 
in units of count rates only. The accompanying SAPRO (SWICS Archive 
Processor) software can be used both to convert the MR count rates to 
physical units (differential flux, phase space density), to correct for 
spillover between different MRs, and to obtain kinetic parameters (density, 
speed, thermal speed) of selected ions (to be used with caution).

Modification History
Data version 1: Original ASCII source data.
Data version 2: Applies to 1996 CDFs onwards, 
which have been replaced using 
ASCII source files generated with a program 
which does not remove low event rate data, 
as was the case for version 1 data. Pre-1996 
files are not reprocessed/replaced as version 2 
as no useful low event rate data exists pre-1996.
For further details contact M. Bruns, 
Max Planck Institut fur Aeronomie, 
Lindau, Germany.
Data version 3: Applies to 1993 data onwards.
In previous versions of data in this period the 
electron channels were in the wrong order in the 
source files, such that data read in the intended order 
ELTL1, EHTL1, ELTL2, EHTL2, ELTL3, EHTL3, ELTL4, EHTL4 
was actually read from fields in the order 
ELTL1, ELTL2, ELTL3, ELTL4, EHTL1, EHTL2, EHTL3, EHTL4 
This version uses corrected source data

UY_PROTON-DISTRIBUTIONS_SWOOPS (spase://NASA/NumericalData/Ulysses/SWOOPS/Proton/ParticleDistributions/PT4M)
Description
This file contains the distribution function of protons. DATA REDUCTION: The
SWOOPS (Solar Wind Observations Over the Poles of the Sun) ion instrument is a
spherical-section curved-plate electrostatic analyzer. Particle arrival
directions are measured in spacecraft coordinates of azimuth (scanned by
spacecraft rotation) and elevation (determined by the detector number) angles.
The spacecraft spin axis was oriented toward the Earth. The energy/charge (E/q)
resolution was ~2.5% while the azimuth (phi) and elevation (theta) resolutions
were both ~5.6o. A description of the SWOOPS is given in a paper by S. J. Bame,
D. J. McComas, B. L. Barraclough, J. L. Phillips, K. J. Sofaly, J. C. Chavez, B.
E. Goldstein, and R. K. Sakurai, Astronomy and Astrophysics Supplement Series,
Ulysses Instruments Special Issue, Vol. 92, No. 2, p.237-265, 1992. The number
of counts in each E/q-phi-theta bin were examined to determine the peak of the
proton and alpha particle distribution, respectively, and the vector magnetic
field (in spacecraft coordinates) was obtained for the time at which the peak
was measured. A "coarse" 2-dimensional matrix was then formed by rotating the
data into a coordinate system with axes parallel and perpendicular to the field
direction. Note that gyrotropy is assumed in making that transformation. The
resolution of the matrix is "coarse" because the vector velocity assigned to
each bin was taken to be at the center of the bin. In reality, the counts in
each bin were probably not smoothly distributed in velocity space over the bin,
but were weighted toward the part of the bin nearest the center of the peak of
the velocity distribution. The "coarse" distribution would thus yield values for
the density and temperature that were higher than the true values. A correction
for that effect was accomplished by fitting contours to the coarse distribution,
breaking each bin or pixel into subpixels, and then using the contours and the
calibrated angular responses to distribute the counts among the subpixels. New
contours were then computed and the process was continued until it converged.
More details about this deconvolution of the angular data are given in the
appendix of a paper by Neugebauer, M., et al., "Ion distributions in large
magnetic holes in the fast solar wind", J. Geophys. Res.,106, 5635, 2001. This
procedure generated the matrix of velocity distribution functions of protons and
alpha-particles parallel and perpendicular to the simultaneously measured
magnetic field.

UY_PROTON-FIT-PARAMETERS_SWOOPS (spase://NASA/NumericalData/Ulysses/SWOOPS/Proton/FitParameters/PT4M)
Description
This file contains  the parameters obtained by fitting data to a bi-maxwellian
core-beam distribution. Under normal circumstances, the first (slow) population
is the core and the second (fast) population is the beam. When the
interplanetary magnetic field is folded back on itself due to turbulence or
other processes the relation of the first and second populations to the core and
beam, respectively, is reversed (see, e.g, M. Neugebauer and B. E. Goldstein,
AIP Conf. Proc. 1539, 46, 2013). The vector magnetic field is given in  RTN
coordinates and it was obtained for the time at which the peak of the proton
distribution function was measured. Only good fits are retained.

UY_PROTON-MOMENTS_SWOOPS (spase://NASA/NumericalData/Ulysses/SWOOPS/Proton/Moments/PT4M)
Description
This file contains the moments obtained from the distribution function of
protons after deconvolution using the same magnetic field values used to
construct the matrices. The vector magnetic field and the particle velocity are
given in inertial RTN coordinates. The magnetic field was obtained for the time
at which the peak of the proton distribution function was measured. The particle
velocity was obtained after rotating the fluid velocity from spacecraft to RTN
coordinates and taking into account the spacecraft velocity. During periods of
spacecraft nutation only the bulk speed and density are reliable, individual
velocity components and temperatures are invalid. The beginning of
scientifically useful SWOOPS data is at Day 322, 00:59 of 1990; at that time the
spacecraft was already nutating; nutation ceased as of Day 351, 22:00, 1990.
There are small systematic uncertainties in the velocity components. These are
due to such effects as uncertainty in the accuracy of alignment on the
spacecraft, relatively wide angular bins, variation in gains between
channeltrons, etc. The velocity component data should not be used for studies of
large scale, long term, solar wind deflection. The data are generally suitable
for all other studies.
