Closed DouglasBoubert closed 6 years ago

DouglasBoubert commented 6 years ago

Added stars from Hattori et al. (2018).

Added parallax offset to Gaia parallaxes.

Fixed mergeradec so it doesn't break if there are no stars with positions.

Decreased corssmatch radius in Simbad crossmatch.

Added correlations between the positions in the case where the star is in Gaia DR2 but only had 2D astrometry.

Gaia querying now first attempts to use Gaia DR2 id for cross-match.
