Description
This is regarding the recent discussion in the science-pipelines room where there has been discussion about using composites to get components of a calexp.
In CameraMapper we will add metadata readers with object constructors for wcs, calib, and visitInfo.
The API to get the components and entire calexp would be
wcs = butler.get(‘calexp_wcs’, dataId={…})
|
calib = butler.get(‘calexp_calib’, dataId={…})
|
visitInfo = butler.get(‘calexp_visitInfo’, dataId={…})
|
calexp = butler.get(‘calexp’, dataId={…})
|
(note: we were originally going to use butler composites for this, but decided this is a better way to go)
