Notes on full-frequency-resolution Galileo PWS LRS spectral list format
The C language code provided in the files pwslist.c, pwscal.h, and pwscal.c
may be compiled and used with the calibration tables in pwslrcal.tab to
generate ASCII calibrated spectral listings given the Galileo PWS LRS
full resolution ("safull") archive files as input. See the file safull.fmt
for a description of these archive files. This document describes the
output of the pwslist program and could be included in a PDS label to
describe a file of the output. The PDS label could describe such a file
as either a TABLE or SPECTRUM.
In the descriptions below, 'interval' refers to the sampling interval over
which the spectrum was accumulated. This is always a 28 minor-frame
instrument cycle which corresponds to 28 mod91 counts of the spacecraft
clock, or 18 2/3 seconds.
In each record, missing or invalid spectral density data are set to zero.
Precise center frequencies for each channel are given in the column
descriptions, however the following generating functions give good
approximations for those frequencies:
SAfreq(c) = 10 ^ ((c + 2.034) / 4.037) for c = 1 .. 4
SFRfreq(c) = 10 ^ ((c + 49.343) / 30.988) for c = 1 .. 106
HFRfreq(c) = 10 ^ ((c + 116.57) / 23.453) for c = 1 .. 42
