As part of the conversion job steps, the metafits file for the observation (containing metadata for the observation) is updated to flag any tiles that failed the calibration quality control (tiles listed in obsid_flagged_tiles.txt). The calibration solutions (in cal_obs.bin) and metadata (obsid.metafits) are applied to the raw visibilities by the COTTER processing cotter processing software and the calibrated visibilities are returned to the MWA ASVO user in one of the standard radio-astronomy formats (CASA measurements set or UVFITS files).
