Target date 2 weeks before ETC 21.1rc1

Improve configuration control of data files used by pysynphot.

This milestone has been deferred yet again.

Complete user-friendly interface for public release. This includes finishing up partially-implemented tickets and completing documentation.

This milestone defines the point at which we have implemented, in pysynphot, all the SYNPHOT functionality that we plan to support. (Some SYNPHOT functionality has already been deprecated due to lack of use.) When this milestone is complete, SYNPHOT can be formally deprecated.

Note: See TracRoadmap for help on using the roadmap.
