FgcmBuildStarsConfig

Configuration fields

apertureInnerInstFluxField

Default

'base_CircularApertureFlux_12_0_instFlux'

Field type

str Field

Full name of instFlux field that contains inner aperture flux for aperture correction proxy

apertureOuterInstFluxField

Default

'base_CircularApertureFlux_17_0_instFlux'

Field type

str Field

Full name of instFlux field that contains outer aperture flux for aperture correction proxy

ccdDataRefName

Default

'ccd'

Field type

str Field

dataRef name for the ‘ccd’ field, usually ‘ccd’ or ‘detector’.

checkAllCcds

Default

True

Field type

bool Field

Check repo for all CCDs for each visit specified. To be used when the full set of ids (visit/ccd) are not specified on the command line. For Gen2, specifying one ccd and setting checkAllCcds=True is significantly faster than the alternatives.

coarseNside

Default

8

Field type

int Field

Healpix coarse Nside for partitioning matches

densityCutMaxPerPixel

Default

1000

Field type

int Field

Density cut number of stars per pixel

densityCutNside

Default

128

Field type

int Field

Density cut healpix nside

doApplyWcsJacobian

Default

True

Field type

bool Field

Apply the jacobian of the WCS to the star observations prior to fit?

doModelErrorsWithBackground

Default

True

Field type

bool Field

Model flux errors with background term?

doReferenceMatches

Default

True

Field type

bool Field

Match reference catalog as additional constraint on calibration

doSubtractLocalBackground

Default

False

Field type

bool Field

Subtract the local background before performing calibration? This is only supported for circular aperture calibration fluxes.

fgcmLoadReferenceCatalog

Default

lsst.fgcmcal.fgcmLoadReferenceCatalog.FgcmLoadReferenceCatalogTask

Field type

ConfigurableField
