I would like to have a location on datasets to collect symlinks to HTM indexed catalogs that can be used by the new multi-reference catalog system:
DM-8232. My suggestion is that it will be called /datasets/ref_cats_htm. There are currently only two catalogs that would be linked there. One is /datasets/refcats/gaia_DR1_v1/photo_astro_ref/, the other is /scratch/ctslater/sdss_dr9_refcat/photo_astro_ref/ which I've asked to be moved to /datasets/refcats/sdss_dr9/photo_astro_ref/ in DM-8672.
I am requesting a new name ref_cats_htm in addition to refcats since we now have two types of catalogs: a.net indexed and HTM indexed. Having a single place for all reference catalogs is probably good. We can then create a collection of just the HTM indexed catalogs in the proposed location.
I do not expect us to be changing the available catalogs often or that we will ever have more than a handful of these. To be concrete, my proposal is that, once
DM-8672 is closed, the structure that looks like the following:
