measurement¶
- Default
- Field type
SingleFrameMeasurementTask configuration
repair¶

Configuration fields¶
averageKeys¶
List of float metadata keys to average when combining snaps, e.g. float positions and dates; non-float data must be handled by overriding the fixMetadata method
badMaskPlanes¶
Mask planes that, if set, the associated pixels are not included in the combined exposure; DETECTED excludes cosmic rays
doDiffIm¶
Perform difference imaging before combining
doMeasurement¶
Measure difference sources (ignored if doDiffIm false)
doPsfMatch¶
Perform PSF matching for difference imaging (ignored if doDiffIm false)
doRepair¶
Repair images (CR reject and interpolate) before combining
initialPsf¶
- Data type
- Field type
InitialPsfConfig configuration
repairPsfFwhm¶
Psf FWHM (pixels) used to detect CRs
sumKeys¶
List of float or int metadata keys to sum when combining snaps, e.g. exposure time; non-float, non-int data must be handled by overriding the fixMetadata method
