Optimized total galactic extinction map (gaiadr3.total_galactic_extinction_map_opt)

The table has 3145728 rows, 7 columns.

Description

This table provides an optimum version of the Total Galactic Extinction map, derived from the table total_galactic_extinction_map at a single HEALPix level 9. For this, the mean effective total Galactic extinction and related uncertainties have been selected from the optimal HEALPix level of the four offered in total_galactic_extinction_map. For further details see Section cu8par_apsis_tge of the online documentation.
