Description
In order to get the DECam camera orientations correct on the sky, we need to flip DECam along X when going between the FOCAL_PLANE and FIELD_ANGLE frames. This parity flip should be encoded in the camera geometry itself, so that we do not need to specify anything special when loading the raw images.
As part of this work, the documentation of how our camera geometry frames relate to each other (afw/doc/lsst.afw.cameraGeom/cameraGeom.rst) will be updated.
This ticket implements RFC-605.
If the work on this ticket does not extend to making this parity flag available via the YAML camera builder, setting that bit in LATISS, and using this in Gen3 formatters and visit definition, we should make sure one or more follow-up tickets for that are created. Depending on who ends up doing this ticket (and when), I could imagine it being easier or harder to keep that work all together or split it up.
