FitTanSipWcsConfig

class lsst.meas.astrom.FitTanSipWcsConfig(*args, **kw)

Bases: Config

Config for FitTanSipWcsTask.

Attributes Summary

maxScatterArcsec	maximum median scatter of a WCS fit beyond which the fit fails (arcsec); be generous, as this is only intended to catch catastrophic failures (float, default 10)
numIter	number of iterations of fitter (which fits X and Y separately, and so benefits from a few iterations (int, default 3)
numRejIter	number of rejection iterations (int, default 1)
order	order of SIP polynomial (int, default 2)
rejSigma	Number of standard deviations for clipping level (float, default 3.0)
