TABLE  vvvBulgeExtMapCoords

Contains details of the 2D pixels positions of the VVV Bulge 3D extinction Map

The 3D Galactic Bulge Extinction Maps from Chen et al.
2013, A&A, 550, A42, Table 1 and 2. Computed using stellar populations
in Besancon model. Uses a combination of VVV and GLIMPSE-II data

Required constraints:
  • Primary key is (pixelID)
  • (mapID) references threeDimExtinctionMaps(mapID)
