Left panel: map of the average extinction affecting the ONC candidate members. The color bar shows the correspondence between the gray scale and visual extinctions.

The overplotted contours represent the AV = 3 (yellow line) and the AV = 6 (red line) levels. Right panel: uncertainty on our derived ON extinction map. See Fig. B.2 for larger views of the left and central panels.
