WcsFactory
(pixelScale, projection, rotation=0 rad, flipX=False)¶ Bases:
object
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?
