STEREO/WAVES 1-minute average files

One minute averages of the STEREO/WAVES data from the low (lfr) and high (hfr) 
frequency receivers are produced in daily files.  For each spacecraft, there 
are 3 files produced each day: (1) an ascii file of the lfr data (48 channels), 
(2) an ascii file of the hfr data (319 channels), and (3) and IDL ‘sav’ file 
that is the sum of lfr and hfr (367 channels) combined into one.  The naming 
convention for the files is:

swaves_average_yyyymmdd_a (or b)_lfr .dat for the lfr ascii data Ahead (Behind)
swaves_average_yyyymmdd_a (or b)_hfr.dat for the hfr ascii data Ahead (Behind)
swaves_average_yyyymmdd_a (or b).sav for the lfr+hfr IDL version

Each file contains (a) a list of the frequencies in the file (in kHz), (b) the 
background value used in (currently) arbitrary decibel (dB) units, (c) the 
2-dimensional (# of frequencies X 1440 minutes per day) array of averages in 
dB above the average (i.e. value-average in dB).  Missing data is indicated by 
a value less than 0.

The specific format for the ascii files is:

(A) f9.1 for frequencies (so, 48f9.1 for lfr or 319f9.1 for hfr)
(B) f8.3 for backgrounds (so, 48f8.3 or 319 f8.3)
(C) f8.3 for the data with each frequency line preceded with an i4 value 
indicating the start minute of the averaging bin (thus, (i4,48f8.3) repeated 
1440 times for lfr and (i4,319f8.3) repeated 1440 times for hfr)

The IDL sav files are self-evident after the usual 'restore' command.
