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.
