11.1 The Visit

The current pipeline requires all data from a single visit to reside in a dedicated directory. The required files are the GEIS files for all three FGSs (.a*h/.a*d), the support schedule file (.dmh), and a pointer to the HST alignment point library. For example, if the FGS visit to be analyzed comprises five individual astrometry observations, then the directory containing the data to be calibrated should contain files shown in Table 11.1 (where PPP and SS are place holders for the actual program_ID and visit ID, respectively). There should be 35 files (5 observations, each with 7 files).
