I wish to estimate the stellar mass of a star using the following observed properties: stellar radius, effective temperature, photometric magnitudes (GAIA + 2MASS + WISE), the measured parallax and an estimate of the reddening or extinction.
I read the relevant section and saw that it seems to be quite straight forward, despite the "observed" extinction. Is it possible to define such a value (which I adopt from an extinction map for example)?
Another issue is about stars with distance > 10 kpc (which is the upper prior limit). For these stars, should I modify the distance prior distribution? Specifically, I am interested in the LMC population.
Dear Timothy,

Thanks a lot, Roy
