NAME = RAD COLUMNS = 11 ROW_BYTES = 32 INTERCHANGE_FORMAT = BINARY PRIMARY_KEY = ( "SPACECRAFT_CLOCK_START_COUNT", "DETECTOR_NUMBER" ) DESCRIPTION = " The RAD table contains the raw and calibrated observed radiances. For each observation there can be up to 6 RAD records, one for each active spectrometer detector. If the Temporal Integration Count (OBS Table, TEMPORAL_AVERAGE_COUNT) is greater than 1, then the data represent the average of the measurements from that many scans. The instrument can apply a programmable spectral mask to the raw data causing neighboring channels to be averaged; however, this feature is used only when downlink bandwidth is limited. When spectrally masked data are received, the averaged-out channels are replaced with the averaged value to expand the spectra back to its original size. The spectral-mask that was used to perform the averaging is kept in this table. The raw spectra are compressed for downlink. The original bit-packed compression header, containing the size of the compressed data and the compression mode used, is kept in this table in order to be used to evaluate the performance of the compressor."
