The "status" fields record the status of the PSF fit for that field in
that filter, and can take the following meanings:
AR_PSF_STATUS_UNKNOWN = -1, /* ??? */ AR_PSF_STATUS_OK = 0, /* PSF fitted by 2nd order parabolas */ AR_PSF_STATUS_PSF22 = 1, /* PSF fitted by linear functions */ AR_PSF_STATUS_PSF11 = 2, /* PSF fitted by a constant */ AR_PSF_STATUS_NOPSF = 3, /* PSF fit from previous frame used*/ AR_PSF_STATUS_ABORTED = 4, /* ??? */ AR_PSF_STATUS_MISSING = 5 /* ??? */"psp_status" is the maximum value of "status" over all 5 filters. The culled field is a bit mask with the same bit values as the primTarget field in the tsObj file. If a bit is set, then all targets of that target type were culled during target selection, and thus this field is excluded from that science sample.
The badMask, acceptableMask, goodMask, and holeMask fields are bit masks indicating which quality categories were set to those qualities. The quality categories (the bits) are:
