[55.09] The New APS Catalog of the POSS I

J. R. Kriessler, R. M. Humphreys, J. E. Cabanela, R. F. Rees Jr., H. Ngo, J. Srivastava (U. Minnesota)

The Automated Plate Scanner (APS) project includes three separate on-line databases or catalogs based on our digitized scans of the POSS I -- the APS Catalog of the POSS I is an object catalog of matched images that contains coordinates, magnitudes, colors, and other image parameters; the high-resolution image database of all detected images, and the new Luyten proper motion database now in progress. A new version of the POSS I objects catalog is now coming on-line with improved classification for faint objects plus other new features. We discuss the development of new Web access tools for the manipulation and visualization of the Catalog and image database including an improved batch query mode and the new federated database for cross-database access. We also discuss our progress toward automated morphological classification for all galaxies in the database with diameters greater than about 15 arcsecs and new software to identify blended images in the object catalog.
