Detailed Description

Convenience class for appending a shifting an input SkyWcs on sky and
appending an affine transform.

The class assumes that all frames are sequential and are mapped one to the
next.

Parameters
----------
input_sky_wcs : `lsst.afw.geom.SkyWcs`
    WCS to decompose and append affine matrix and shift in on sky
    location to.

		inputSkyWcs
	)

Member Function Documentation

◆ makeWcs()

def lsst.meas.astrom.fitAffineWcs.TransformedSkyWcsMaker.makeWcs	(	self,
		crvalOffset,
		affMatrix
	)

Apply a shift and affine transform to the WCS internal to this
class.

A new SkyWcs with these transforms applied is returns.

Parameters
----------
crval_shift : `numpy.ndarray`, (2,)
    Shift in radians to apply to the Wcs origin/crvals.
aff_matrix : 'numpy.ndarray', (3, 3)
    Affine matrix to apply to the mapping/transform to add to the
    WCS.

Returns
-------
outputWcs : `lsst.afw.geom.SkyWcs`
    Wcs with a final shift and affine transform applied.
