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?

Make a Wcs. Parameters ---------- crPixPos : `lsst.geom.Point2D` crPix for WCS, using the LSST standard. crValCoord : `lsst.geom.SpherePoint` ICRS crVal for WCS. Returns ------- results : `lsst.afw.geom.SkyWcs` The new SkyWcs object.
