MatchTolerancePessimistic¶
- 
class lsst.meas.astrom.MatchTolerancePessimistic(maxMatchDist=None, autoMaxMatchDist=None, maxShift=None, lastMatchedPattern=None, failedPatternList=None)¶
- Bases: - lsst.meas.astrom.MatchTolerance- Stores match tolerances for use in AstrometryTask and later iterations of the matcher. - MatchPessimisticBTask relies on several state variables to be preserved over different iterations in the AstrometryTask.matchAndFitWcs loop of AstrometryTask. - Parameters: - maxMatchDist : lsst.geom.Angle
- Maximum distance to consider a match from the previous match/fit iteration. 
- autoMaxMatchDist : lsst.geom.Angle
- Automated estimation of the maxMatchDist from the sky statistics of the source and reference catalogs. 
- maxShift : lsst.geom.Angle
- Maximum shift found in the previous match/fit cycle. 
- lastMatchedPattern : int
- Index of the last source pattern that was matched into the reference data. 
- failedPatternList : listofint
- Previous matches were found to be false positives.
