Each value in the TABLE is the standard deviation of 100 DN samples for a known input charge. The values in this TABLE apply to one SDC channel (04), and each COLUMN corresponds to one temperature. The ROW indicates the order in which the samples were taken at each temperature; there is no correlation across COLUMNs on each ROW between the input charges that generated the values, and values in later ROWs are sometimes zero indicating that fewer than 19 calibration runs resulted in non-zero values. This TABLE is one of several archiving calibration parameters used in the calibration of SDC data. Details of the calibration may be found in the SOC ICD document, which was delivered with this data set. Genesis of the calibration data (from the ICD): In a temperature controlled environment, the electronics from the end of the PVDF to the DN in the raw data were calibrated, at each of 4 calibration box temperatures and for each of the 14 channels. This was done by injecting 19 (actually 21; see the ICD) fixed-amplitude charge pulses 100 times into a channel and recording the DN value each time. From those recorded values, the average DN (DNavg) and its standard deviation (SIG) at each charge pulse amplitude, box temperature and channel were calculated. Then, for each box temperature and channel, a 9th order polynomial fit of Q(DNavg) was derived. Finally, these 3 sets of values (the polynomial coefficients, DNavg, and SIG) were stored in a matrix. This matrix contains all information required to calculate the charge equivalent to a DN as a function of box temperature and channel (detector), as well as the uncertainty in that calculated charge value. That matrix has been broken out into forty-two PDS ASCII TABLEs; this TABLE is one of those forty-two.
