MCMC samples for GSP from Photometry

Listed in Gaia@AIP

Description

<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<sub>eff</sub> in K <li> monochromatic extinction at 547.7~nm A<sub>0</sub> in mag <li> surface gravity log g <li> metallicity [M/H] <li> G-band extinction in mag <li> absolute magnitude M<sub>G</sub> in mag <li> distance in pc <li> G<sub>BP</sub> band extinction A<sub>BP</sub> in mag <li> G<sub>RP</sub> band extinction A<sub>RP</sub> in mag <li> reddening E(G<sub>BP</sub> - G<sub>RP</sub>) = A<sub>BP</sub> - A<sub>RP</sub> in mag <li> logarithmic posterior probability <li> logarithmic likelihood <li> stellar radius in R<sub>&#8857;</sub> </ul></p>
