... Previous: Why Indexing the Sky is Desirable . ... An alternative algorithm, proposed here, is based on covering the sky with pixels of approximately equal area, and assigning a unique integer to each pixel. ... For each table, the pixel code value corresponding to the central position (RA, Dec) of each source is computed and inserted into a new column called PCODE. ... This cannot be the primary index of a table since PCODE values are not necessarily unique: one pixel may contain more than one...

... I am a postdoc at the Arcetri Astrophysical Observatory in Florence (IT) as a member of the Galaxies, AGN, and Cosmology Group . My research is focused on the analysis of the physical properties of galaxies which host an actively accreting black hole in their center, the so-called Active Galactic Nuclei (AGN), and of the interplay between AGN and host-galaxy. Most of my research is carried out in the context of the XMM-Newton wide field survey in the COSMOS field. б  . ...
