createInitialSkyWcs¶
- lsst.obs.base.createInitialSkyWcs(visitInfo, detector, flipX=False)¶
Create a SkyWcs from the visit information and detector geometry.
A typical use case 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 geometry from.
- flipX
bool
, optional If False, +X is along W, if True +X is along E.
- visitInfo
- Returns:
- skyWcs
lsst.afw.geom.SkyWcs
The new composed WCS.
- skyWcs
- Raises:
- InitialSkyWcsError
Raised if there is an error generating the SkyWcs, chained from the lower-level exception if available.
