Notes

Copyright and such: The field metadata were, in part, taken from CDS' Vizier service.

The Data Center is currently running in emergency mode after our database server failed catastrophically (see our blog for infos and updates).

This means, in particular, that services built on top of large tables may currently be broken. Since our replacement server is much slower than our usual machine, restoring them will take quite some time.
