"Documentation" of WAVES 1-minute averages


Even though we agreed years ago to keep everything in level zero
format, I've gone ahead on my own creating one minute average files
for rad1, rad2, and tnr.  I did this because it takes too long to
make a plot starting with level zero data, particularly if you want 
to do a multiday plot -- several hours for tnr, for example. 

For the rads, files are arrays that are 1441 X 256 -- 256 for the 
channels (and yes I already do the interpolation for times when we're 
in SUM mode), and 1440 for every minute of the day with position 1441 
reserved for the background values  (and there are only background entries 
for 'real' channels -- i.e. those that the receiver actually samples 
rather than interpolated frequencies).  For the tnr I have daily arrays 
that are 1441 X 96 (no interpolation here). All values are in terms of 
ratio to background and the background values are listed in position 1441 
in microvolts per root Hz.  [Note that this is NOT the complete answer
for those seeking absolute power (or voltage) because the antenna function
has not been taken into account.  These values are the direct output from
Wind_lib -- fine for dynamic spectra or relative comparisons, but not
fine if you need absolute power]

So much for documentation.  By 'restoring' these files, one can plot
a dynamic spectrum in a matter of seconds -- I have a dynamic
spectra program that will plot rad or tnr dynamic spectra for
anything from 1 minute to 30 days. Grab all the *.pro files in my
anonymous ftp 'pub' directory.  You'll have to change a few lines as
indicated in the main program (wavesdsp).

For those of you lucky enough to work at Goddard, I am exporting the
data on the LAN.  The three directories are:

lepmlk.gsfc.nasa.gov:/usr1/rad1  (for rad1)
lepmlk.gsfc.nasa.gov:/usr2/rad2  (for rad2)
lepmlk.gsfc.nasa.gov:/usr3/tnr   (for tnr)

Just add them to your automounter or whatever, and you should be able to
acces the data.  For the rest of you, I can provide a 4-mm DAT in tar
format if you ask me.
