DR3SelectionFunction

class gaiaunlimited.selectionfunctions.DR3SelectionFunction(*args, **kwargs)

Bases: DR2SelectionFunction

DR3 selection function developed by the Gaiaverse team.

This selection function assumes the same detection probability and simply swaps the number of scans map (since DR3 covers a longer mission time). The map resolution also changed from HEAL order 12 (nside=4096) to order 10 (nside=1024).
