Resumen:
I develop an empirical method to caracterize the position and shape of the missing parts on a photometric sample in a reduced area. The algorithm searches for holes depending on the density of objects in projection. The border points are linked using a percolation algorithm in order to isolate different holes, described by polygons. The obtained masks for fields in the Sloan Survey are used to calculate the density profile of galaxies in RASS groups.
