Detailed Description

A factory for creating Wcs objects for the sky tiles.

Parameters
----------
pixelScale : `lsst.geom.Angle`
    Desired scale, as sky/pixel.
projection : `str`
    FITS-standard 3-letter name of projection, e.g.: TAN (tangent),
    STG (stereographic), MOL (Mollweide's), AIT (Hammer-Aitoff)
    see Representations of celestial coordinates in FITS
    (Calabretta and Greisen, 2002).
rotation : `lsst.geom.Angle`
    Rotation relative to cardinal.
flipX : `bool`
    Flip the X axis?

makeWcs()

def lsst.skymap.detail.wcsFactory.WcsFactory.makeWcs	(		self,
			crPixPos,
			crValCoord
	)

Make a Wcs.

Parameters
