The Automated Plate Measuring Machine (APM) is located at the Institute of Astronomy, Cambridge, UK. It has been used to scan the POSS-I survey plates at galactic latitudes above abs(b) = 20 deg. Both colors were scanned and objects cross-identified, so that color information is available (so far unique in all-sky surveys) for a matched object catalog of well over 100 million objects down to m=22 in blue (O) and m=20 in red (E). At this time, no copies of the entire catalog are distributed, but potential users will be given access to smaller subsets for their own use. The northern hemisphere catalog above 3 deg. declination is available for routine interrogation and the southern hemisphere catalog based on UKST Bj and R plates is about half complete and also available. A captive account for remote catalog interrogation can be accessed via telnet to 131.111.68.56, login as user catalogues and follow the instructions. Contact: M. Irwin (mike@mail.ast.cam.ac.uk or R.
