Color profile of the SDSS g−i map used for the dust correction. The best-fitting linear line obtained by a robust fit is shown in green. We decided the red line to be the threshold in order to assure the same width of the gradient under the line-fit and above. All pixels above the red line and for log (d) < 1.9 ( ≈ 80) [arcsec] were corrected for extinction.
