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 " OBJECT = COLUMN NAME = SCET COLUMN_NUMBER = 1 DATA_TYPE = CHARACTER START_BYTE = 1 BYTES = 24 DESCRIPTION = " SCET of the beginning of the interval in PDS time format, e.g. '1996-06-27T00:00:00.000Z'."
