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 Control Document [5] (see § 1.2). 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.
