data/ contains map data (in FITS format) and the polynomials of the empirical correction for the Gaia synthetic photometry.
figures/ contains additional figures, including
    dr9_offset_corrected/ maps of the magnitude offset after the smooth varying offset at DEC<-29.25 is removed
    median_offset/ maps and histograms of the magnitude offset
    number_of_stars/ maps of the number of stars (in each pixel) used in the magnitude offset calculation
    scatter/ maps of the photometric scatter (in normalized median absolute deviation) within each pixel
