class lsst.meas.astrom.MatchOptimisticBConfig(*args, **kw)#

Bases: Config

Configuration for MatchOptimisticBTask

Attributes Summary

`allowedNonperpDeg`	Allowed non-perpendicularity of x and y (degree) (`float`, default `0.2`)
`maxDeterminant`	maximum determinant of linear transformation matrix for a usable solution (`float`, default `0.02`)
`maxMatchDistArcSec`	Maximum separation between reference objects and sources beyond which they will not be considered a match (arcsec) (`float`, default `2.0`)
`maxOffsetPix`	Maximum allowed shift of WCS, due to matching (pixel).
`maxRotationDeg`	Rotation angle allowed between sources and position reference objects (degrees) (`float`, default `1.0`)
`minFracMatchedPairs`	Minimum number of matched pairs as a fraction of the smaller of the number of reference stars or the number of good sources; the actual minimum is the smaller of this value or minMatchedPairs (`float`, default `0.3`)
`minMatchedPairs`	Minimum number of matched pairs; see also minFracMatchedPairs (`int`, default `30`)
`numBrightStars`	Maximum number of bright stars to use in fit.
`numPointsForShape`	number of points to define a shape for matching (`int`, default `6`)

Attributes Documentation

allowedNonperpDeg#

Allowed non-perpendicularity of x and y (degree) (float, default 0.2)

Valid Range = [-inf,45.0)

maxDeterminant#: maximum determinant of linear transformation matrix for a usable solution (float, default 0.02)

maxMatchDistArcSec#

Maximum separation between reference objects and sources beyond which they will not be considered a match (arcsec) (float, default 2.0)

Valid Range = [0,inf)

maxOffsetPix#

Maximum allowed shift of WCS, due to matching (pixel). When changing this value, the LoadReferenceObjectsConfig.pixelMargin should also be updated. (int, default 250)

Valid Range = [-inf,4000)

maxRotationDeg#

Rotation angle allowed between sources and position reference objects (degrees) (float, default 1.0)

Valid Range = [-inf,6.0)

minFracMatchedPairs#

Minimum number of matched pairs as a fraction of the smaller of the number of reference stars or the number of good sources; the actual minimum is the smaller of this value or minMatchedPairs (float, default 0.3)

Valid Range = [0,1)

minMatchedPairs#

Minimum number of matched pairs; see also minFracMatchedPairs (int, default 30)

Valid Range = [2,inf)

numBrightStars#

Maximum number of bright stars to use in fit. (int, default 150)

Valid Range = [2,inf)

numPointsForShape#: number of points to define a shape for matching (int, default 6)
