Review possibilities for photometric redshifts from Roman catalogs #1238

Issue RCAL-840 was created on JIRA by Eddie Schlafly:

There are a number of potential photometric redshift algorithms under consideration for Roman.  Review the available documentation on these and try to evaluate whether using these within Roman makes sense.

Comment by Eddie Schlafly on JIRA:

I'm proposing a baseline of rail + BPZ following a review.  The BPZ code base has seen some effort from the rail folks and exists as a nice python package.  It's template-based and so would be straightforward to implement ~today in the absence of real training data.  Using rail as an intermediate layer will make it easier for us to change our mind later if we need to.
