CALIB_STATUS: Calibration status for an SDSS image
In the flat files there are arrays of length five for each band
calib_status[5]
ordered
u,g,r,i,z
. In the CAS these are named by
band pass calibstatus_{band}
.
Bit name | Binary digit | Description |
---|---|---|
PHOTOMETRIC | 0 | Photometric observations |
UNPHOT_OVERLAP | 1 | Unphotometric observations, calibrated based on overlaps with clear, ubercalibrated data; done on a field-by-field basis. Use with caution. |
UNPHOT_EXTRAP_CLEAR | 2 | Extrapolate the solution from the clear part of a night (that was ubercalibrated) to the cloudy part. Not recommended for use. |
UNPHOT_EXTRAP_CLOUDY | 3 | Extrapolate the solution from a cloudy part of the night (where there is overlap) to a region of no overlap. Not recommended for use. |
UNPHOT_DISJOINT | 4 | Data is disjoint from the rest of the survey (even though conditions may be photometric), the calibration is suspect. Not recommended for use. |
INCREMENT_CALIB | 5 | Incrementally calibrated by considering overlaps with ubercalibrated data |
RESERVED2 | 6 | reserved for future use |
RESERVED3 | 7 | reserved for future use |
PT_CLEAR | 8 | (INTERNAL USE ONLY in DR8 and later) PT calibration for clear data |
PT_CLOUDY | 9 | (INTERNAL USE ONLY in DR8 and later) PT calibration for cloudy data |
DEFAULT | 10 | (INTERNAL USE ONLY in DR8 and later) a default calibration used |
NO_UBERCAL | 11 | (INTERNAL USE ONLY in DR8 and later) not uber-calibrated |
