The vimos_ima_standard recipe =============================================================== .. data:: vimos_ima_standard Synopsis -------- Standard field processing for imaging Description ----------- vimos_ima_standard -- VIMOS standard star recipe. Take a list of standard frames and correct them to remove bias, dark and flat field signatures. Optionally defringe the reddest filter images. Astrometrically and photometrically calibrate the individual images, but do no stacking The program accepts the following files in the SOF: Tag Description STD A list of raw standard images MASTER_BIAS A master bias frame MASTER_DARK A master dark frame MASTER_TWILIGHT_FLAT A master flat frame MASTER_CONF A master confidence map MASTER_FRINGE A master fringe map (optional) MASTER_FRINGE_VAR A master fringe variance map (optional) MASTER_READGAIN A master readgain table MASTER_2MASS_CATALOGUE_ASTROM A master 2MASS index for astrometry or MASTER_PPMXL_CATALOGUE_ASTROM A master PPMXL index for astrometry or MASTER_APASS_CATALOGUE_ASTROM A master APASS index for astrometry or MASTER_LOCAL_CATALOGUE_ASTROM A master local catalogue index for astrometry MASTER_APASS_CATALOGUE_PHOTOM A master APASS index for photometry or MASTER_LOCAL_CATALOGUE_PHOTOM A master local catalogue index for photometry PHOTCAL_TAB A photometric calibration table SCHLEGEL_MAP_NORTH Northern Schlegel Map SCHLEGEL_MAP_SOUTH Southern Schlegel Map All of these are required unless specified otherwise.
