Results presented here are based on the bibliomatrix site (NASA-ADS based).
The impact factor and total citations numbers have been computed using refereed astrophysical papers only starting from 2000.   
I used INAF personell and universities affiliated lists updated up to 2005 (available on the bibliomatrix site).

Notes: 

What is the impact factor:  The impact factor, often abbreviated IF, is a measure of the citations to science and social science journals. It is frequently used as a proxy for the importance of a journal to its field. The Impact factor was devised by Eugene Garfield, the founder of the Institute for Scientific Information, now part of Thomson, a large worldwide US-based publisher. Impact factors are calculated each year by Thomson Scientific for those journals which it indexes, and the factors and indices are published in Journal Citation Reports. The publication of each year covered occurs in the summer of the following year.

How is the Impact Factor been calculated:

Impact factors (IF) issued by Thomson ISI are copyrighted so cannot be used here. We used however data that has been gathered online in various places and that is believed to be in the public domain. These are IF issued by publishers and libraries and normally coincide with ISI data, although are not updated. Most of the IF used here refer to the years 2000-2001 but they are applied uniformly to all entries regardless of the year. So, the IF statistics of Bibliomatrix is a very rough approximation. Entries without IF (usually unrefereed material) is assigned zero IF. The IF effectively employed will be listed in the result page.
