The git repository for astrometry_net_data contains a token representation of the CFHT data and the README guidance on acquiring USNOB data.
Neither of these two datasets, as-is, have had recent-past use.
Option 1: This Issue is to resolve whether they should be carried indefinitely in the git repository as they now stand; or
Option 2: Reconsider how we setup, maintain, and programatically access the various astrometry_net_data datasets and then implement the new specification.
Option 3: Perhaps this is an ancillary task to developing a new specification for how we maintain and access the different types of datasets we use: ephemerides and test data.
The options run from Trivial importance for Option 1, Minor importance for Option 2, and Major importance for the overarching Option 3.
