Configuration fields

badMaskPlanes

Default
('NO_DATA', 'SUSPECT')
Field type
str ListField
Mask planes that, if set, the associated pixel should not be included sky noise calculation.

clipIter

Default
2
Field type
int Field
Number of iterations of outlier rejection for sky noise.

psfBadMaskPlanes

Default
('BAD', 'CR', 'EDGE', 'INTRP', 'NO_DATA', 'SAT', 'SUSPECT')
Field type
str ListField
Mask planes that, if set, the associated pixel should not be included in the PSF model robutsness metric calculations (namely, maxDistToNearestPsf and psfTraceRadiusDelta).

psfGridSampling

Default
96
Field type
int Field
Sampling rate in pixels in each dimension for PSF model robustness metric caclulations grid (the tradeoff is between adequate sampling versus speed).

psfSampling

Default
8
Field type
int Field
Sampling rate in pixels in each dimension for the maxDistToNearestPsf metric caclulation grid (the tradeoff is between adequate sampling versus speed).

psfShape

Default
'slot_PsfShape'
Field type
str Field
Base name of columns to use for the PSF shape in the PSF statistics computation.

sigmaClip

Default
3.0
Field type
float Field
Sigma for outlier rejection for sky noise.

starSelection

Default
'calib_psf_used'
Field type
str Field
Field to select sources to be used in the PSF statistics computation.

starShape

Default
'slot_Shape'
Field type
str Field
Base name of columns to use for the source shape in the PSF statistics computation.
