analogous to the WD LF paper, let's look at the lower/lowest MS; just brain dump; needs follow-up.
Question: what is the "bimodality"?
Query
SELECT top 16000 *
FROM gaiaedr3.gaia_source AS g
WHERE
g.phot_g_mean_mag < 19.5
and
g.parallax > 20.
and
g.phot_g_mean_mag +5*log10(g.parallax)-10 > 11.
and
g.bp_rp > 2.
Plot
at some point one could look at optical spectra, to understand the color-bimodality:
