It should not " - "be considered as highly " - "accurate data. For " - "example, accurate data " - "requires a correction in " - "the form of an offset to " - "the Sunward component of " - "the electric field. A " - "constant offset of 1.2 " - "mV/m has been used for all" - " the data, this being an " - "approximate average value." - " In fact, however, the " - "offset varies with time, " - "and must be determined by " - "analysis of the particular" - " time of interest. Users " - "of this data desiring more" - " information should get in" - " touch with Dr. Forrest " - "Mozer, at the Space " - "Sciences Laboratory, " - "University of California, " - "Berkeley." } 2: CDF_CHAR { "The electric field data is" - " at spin period time " - "resolution. This means " - "that there is 1 data point" - " about every 6 seconds. " - "However, it should be " - "noted that there can be " - "longer intervals between " - "data points, due to " - "missing data. Data gaps " - "are not filled in." } 3: CDF_CHAR { "The components of the " - "electric field are given " - "in a coordinate system " - "designated as Despun " - "Spacecraft Coordinates , " - "or DSC. This is a " - "coordinate system for a " - "rotating spacecraft that " - "is in an orbit near the " - "Earth. DSC is defined by " - "the spacecraft's spin " - "plane and spin axis. " - "However, as the Despun " - "part of the name suggests," - " the coordinate axes do " - "not participate of the " - "spacecraft's rotation. The" - " X and Y axes are on the " - "spacecraft's spin plane; " - "the Z axis is along the " - "spacecraft's spin axis. " - "The positive X, Y, and Z " - "axes form an orthogonal, " - "right-handed coordinate " - "system. The positive Z " - "axis points in the same " - "direction as the " - "spacecraft's angular " - "momentum (or spin or " - "attitude) vector. The " - "positive X axis points in " - "the direction on the spin " - "plane that is closest to " - "the direction towards the " - "Sun. In other words, the " - "positive X axis points in " - "the direction of the " - "projection on the spin " - "plane of the vector from " - "the spacecraft to the Sun." - " The positive Y axis is " - "determined by the " - "requirement that the DSC " - "system (X, Y, Z) be an " - "orthogonal right-handed " - "system. It follows that " - "the positive Y axis points" - " in the direction on the " - "spin plane that is 90 " - "degrees ahead of the " - "positive X axis (in the " - "sense of the spacecraft's " - "rotation). " } 4: CDF_CHAR { "The electric field data " - "included in these files " - "consists of 2 electric " - "field components on the " - "spin plane. The original " - "data used is V34L, which " - "typically has a time " - "resolution of about 40 " - "data points per second. A" - " least-squares spin fit of" - " V34L is performed, and " - "the spin fit coefficients " - "provide the spin plane " - "components of the spin " - "period electric field. " } 5: CDF_CHAR { "Time is a real " - "double-precision quantity." - " The units for the time " - "are seconds. The time is " - "time elapsed since the " - "FAST Mission Epoch, which " - "is May 24, 1968 " - "(1968/05/24) at 00:00:00 " - "UT. Each time tag " - "indicates the mid-point of" - " the time interval for the" - " corresponding spin " - "period. Data gaps are not" - " filled; each time tag " - "corresponds to an actual " - "data point. " } 6: CDF_CHAR { "X, Y, and Z are the 3 " - "components of the attitude" - " vector in the GSE " - "coordinate system (note " - "that all 3 X, Y, and Z " - "components are present, " - "despite the X in the file " - "name).
