41.4 HSP Calibration Parameter Tables

Table 41.3 lists the HSP calibration parameters as found in the Calibration Data Base (CDBS). When using calhsp, CDBS values are read into STSDAS binary tables. The tables are required in order to run a complete calibration of the data. These tables are all stored in the HST Archive and can be retrieved from there as described in Chapter 1.
