			Hi Pascale, hi Nicolas,

			So here is the background-subtracted PAndAS catalogue with some extra columns:

			In particular, the column imag0_abs_corrected lists the extinction corrected absolute i-band magnitude of each star, corrected to account for the missing stars in the stellar population that we don’t get to detect due to the magnitude limit of i=23.5.


			Here’s a fits image file of the i-band surface brightness in PAndAS using pixels of size (1/10 deg)x(1/10 deg):

			which I made from the above catalogue using this little python script:

			The above image looks like this in ds9:


			As you can see from the colorbar, the PAndAS catalogue has a very faint equivalent surface brightness. The giant stream lies at around 29 mags/arcsec^2, and the fainter streams are at ~31-32 mags/arcsec^2.

			I hope this helps!

			all the best

			Rodrigo



			Pour construire cette carte, j’ai fait la supposition que PAndAS est complet jusqu’a i=23.5 (comme avant). La carte tient en compte et corrige la luminosité en bande g des populations non-résolues en étoiles par PAndAS (en fonction de g-i).
