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 cu8par_apsis_gspphot 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: effective temperature T<sub>eff</sub> in K monochromatic extinction at 547.7~nm A<sub>0</sub> in mag surface gravity log g metallicity [M/H] G-band extinction in mag absolute magnitude M<sub>G</sub> in mag distance in pc G<sub>BP</sub> band extinction A<sub>BP</sub> in mag G<sub>RP</sub> band extinction A<sub>RP</sub> in mag reddening E(G<sub>BP</sub> - G<sub>RP</sub>) = A<sub>BP</sub> - A<sub>RP</sub> in mag logarithmic posterior probability logarithmic likelihood stellar radius in R<sub>⊙</sub>
