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.

Constructor & Destructor Documentation

◆ init()

lsst.meas.astrom.fitAffineWcs.TransformedSkyWcsMaker.__init__	(		self,
			inputSkyWcs )

Definition at line 223 of file fitAffineWcs.py.

Member Function Documentation

◆ makeWcs()

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

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

A new SkyWcs with these transforms applied is returns.

Parameters
----------
linearShift : `numpy.ndarray`, (2,)
    A linear shift to apply at the same time as applying the affine
    matrix transform.
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.
