Abstract

The Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) project is an observing system to support wide-field survey observing programs for a multitude of scientific objectives. The composite images of the sky that will be produced over the 3.5 year mission of the PS-1 prototype telescope are expected to yield over 5 billion distinct objects. A significant fraction of these sources will be measured up 60 times through filters on the Sloan g, r, i, z, and y system thus providing information on their time history.

A major challenge for the Pan-STARRS project has been the design of our database, the Object Data Manager (ODM), that will keep track of the catalogs of these objects in the stationary sky, their associated time-history of detections, and provide an interface that will allow users to access these data. The ODM is a key component of the Pan-STARRS Published Sciences Products Subsystem (PSPS). In this poster we describe the the challenges presented by the ODM design, how it fits into the PSPS, and the prototype design we are working on to build an ODM that will handle an order of magnitude more distinct objects found in either the SDSS or 2MASS surveys.
