File an RFD requesting information about current and possible future use cases for a Wcs system in the stack. This should get feedback from, at minimum, the alerts pipeline, DRP, and Level III data producers. It should also get feedback from our resident wcs experts.
Whether those use cases are currently implemented in our code, or could be generalized from it, isn't important to this RFD as this information will feed into a subsequent requirements document and RFC about what needs to be written/changed.
Some use cases/buzzwords that will likely be included:
- Efficient x,y -> x',y'
- Stacking a sequence of transformations efficiently
- easy extensibility
- should color terms be included in the Wcs or dealt with elsewhere?
- pixel distortion effects (e.g. tree rings, edge roll off)
- Simultaneous Astrometry (i.e. from image stacks)
