The level1a data were derived from the following raw data file(s): grd_191pb_171650000_16900_0.dat Each row contains level1a science data that has been tagged with the SCET_UTC time and SCLK tics for the first packet of the corresponding science data record. The process of converting raw science data records to level1a records involves separating the science data from the packet headers, decoding and unscrambling the event mode data, and decompressing the histograms. This file contains a time series of scaler data from the APID191 state-of-health telemetry file (23 scalers defined in the Level1a catalog file). " END_OBJECT = TABLE END
