There are catalogs of interest spread across the kowalski, gloria, and melman machines. It would be optimal to be able to use one query to get data without needing to specify the machine on which it resides.

A good longer-term solution could be sharding (e.g. here). For the short term, see this PR to penquins that introduces a new KowalskiInstances class that authenticates each machine and queries the one containing the catalog of interest. If/when this PR gets approved, we should revise the scope code to include this functionality, preempting confusion amid the growing number of machines.

This is now possible thanks to Theo's kowalski/penquins updates.
