daschlab.plates Module

Tables of information about photographic plates.

The main class provided by this module is Plates, instances of which can be obtained with the daschlab.Session.plates() method.

The nomenclature in this module somewhat glosses over the distinction between physical plates and “mosaics”, which is the DASCH terminology for a single large image made from a scan of a plate. Multiple mosaics of a single plate can, in principle, exist. To a good approximation, however, there is a 1:1 relationship between the two.
