WcsFactory¶
- class lsst.skymap.detail.WcsFactory(pixelScale, projection, rotation=Angle(0, degrees), 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?
- pixelScale
