BGS SV fields

[changhoonhahn]

BGS SV fields were revised back in April in order to maximize overlap with the DR9 SV footprint. At the time, SV was scheduled to happen before DR9 would be processed for the full footprint. So, DR9 imaging would be run on these SV regions, specified in the link, first. Now that this is not an issue we may want to revisit the BGS SV fields.

Here's the BGS SV fields from April --- selected using this notebook

Potential to dos:

-- Revisit CMX TILEIDs, making sure any tile with same ID has the same center.
-- Prioritize the fields.
-- Check we didn't lose avoiding shallow GAMA data, and pointing at the deeper GAMA data.
-- PAU & JPAS overlap?
