createInitialSkyWcs
(visitInfo, detector, flipX=False)¶ Create a SkyWcs from the visit information and detector geometry.
A typical usecase for this is to create the initial WCS for a newly-read raw exposure.
Parameters: - visitInfo :
lsst.afw.image.VisitInfo
Where to get the telescope boresight and rotator angle from.
- detector :
lsst.afw.cameraGeom.Detector
Where to get the camera geomtry from.
- flipX :
bool
, optional If False, +X is along W, if True +X is along E.
Returns: - skyWcs :
lsst.afw.geom.SkyWcs
The new composed WCS.
Raises: - InitialSkyWcsError
Raised if there is an error generating the SkyWcs, chained from the lower-level exception if available.
