Add reference catalog loader notebook #254

Closed bechtol closed 3 years ago

bechtol commented 3 years ago

The PR provides an example of loading a reference catalog with color terms and proper motions applied.

Not yet ready for review.

Expanded documentation. Also, it appears that the reference catalog loader is not incorporated in the main branch of lsst.pipe.tasks so I think this is now ready for review.

I was able to run the notebook successfully on the NCSA RSP. This was the first time I encountered butler.getDirect and butler.getDeferred. Maybe some additional description of these two functions could be added in a future update.
