V1:
611689 data instances filtered from gaia DR3.

100k instances for each spectral class : A, F, G, K, M.
85673 for B type stars.
26016 for O type stars.

Information of columns:

RA_ICRS: Right ascension in the ICRS (International Celestial Reference System) coordinate system.
DE_ICRS: Declination in the ICRS coordinate system.
Source: Unique identifier for an object in the Gaia catalogue.
Plx: Trigonometric parallax of the celestial body in milliarcseconds.
PM: Total proper motion of the celestial body in the sky in milliarcseconds per year.
pmRA: Proper motion component in the right ascension direction in milliarcseconds per year.
pmDE: Proper motion component in the declination direction in milliarcseconds per year.
Gmag: Average apparent magnitude integrated in the G band.
e_Gmag: Error in G magnitude.
BPmag: Average apparent magnitude integrated in the BP blue band.
e_BPmag: Error associated with BP magnitude.
RPmag: Average apparent magnitude integrated in the RP red band.
e_RPmag: Error in RP magnitude.
GRVSmag: Average apparent magnitude integrated in the RVS band.
e_GRVSmag: Error in RVS magnitude.
BP-RP: BP-RP color index.
BP-G: BP-G color index.
G-RP: G-RP color index.
pscol: pseudocolor estimated by gaia in um^-1
Teff: Estimated effective temperature of the celestial object by Gaia in Kelvins.
Dist: Distance to the celestial object: inverse of the parallax, in parsecs.
Rad: Object radius estimate in terms of solar radius.
Lum-Flame: Estimated object luminosity in terms of solar luminosity.
Mass-Flame: Mass estimate in terms of solar mass.
Age-Flame: Celestial object age in giga years.
z-Flame: Redshift in km/s.
SpType-ELS: Estimated spectral class by Gaia.
