Dear all I have significantly changed and put more details in the AstroGrid 2 bid - see section 4.2 and its sub-sections in http://wiki.astrogrid.org/bin/view/AG2/AgVirObInf I believe that it now fits in better with the rest of the AstroGrid bid and clarifies and reduces apparent overlap with other areas. I have also added to the ESO bid - see http://wiki.starlink.ac.uk/twiki/bin/view/Starlink/ESODataProcessing I'd appreciate comments on both ASAP, and those who can, please add things directly to the ESO bid document. ..David
