10.17876/gaia/dr.3/45MCMC samples for GSP from PhotometryEuropean Space Agency (ESA)DPAC ConsortiumAstronomyLeibniz Institute for Astrophysics Potsdam (AIP)<p>This is the DataLink table hosting Monte-Carlo Markov Chain (MCMC) samples for the posterior probability distribution of all parameters derived from the General Stellar Parametrizer from Photometry (GSP-Phot, see Section&nbsp;<a href="ssec:cu8par_apsis_gspphot">cu8par_apsis_gspphot</a> in the online documentation). 2000 MCMC samples are provided for 1) all sources brighter than G=12, 2) a random subset of 0.1% of the sources fainter than G=12. For all other sources fainter than G=12, the sample size is 100 (the last 100 samples in the MCMC).The table considers the following parameters:<ul> <li> effective temperature T_eff in K <li> monochromatic extinction at 547.7~nm A₀ in mag <li> surface gravity log g <li> metallicity [M/H] <li> G-band extinction in mag <li> absolute magnitude M_G in mag <li> distance in pc <li> G_BP band extinction A_BP in mag <li> G_RP band extinction A_RP in mag <li> reddening E(G_BP - G_RP) = A_BP - A_RP in mag <li> logarithmic posterior probability <li> logarithmic likelihood <li> stellar radius in R_&#8857; </ul></p>2022-06-13BY_NC_IGDataset
