6.1.3 Listing the OM Current Calibration Files

Table 11 provides a list of the OM calibration files. For a detailed description of these files and of their usage, the user is referred to the CCF interface document and to the Calibration Access and Data Handbook (see § 1.4). Some of these files are only used by the real time PHS and QLA systems, although they are contained in the SAS file ccf.cif. The SAS tasks using a given CCF are indicated as well.
