DIGITIZATION, ARCHIVING AND DISSEMINATION OF THE 275 GBYTES OF THE AAO UKST H-ALPHA SURVEY DATA/

We plan to digitise the AAO/UKST H alpha survey of the Southern sky us ing the SuperCOSMOS facility at the Royal Observatory Edinburgh. The d igitisation will be performed at 10 microns resolution (0.67 arcsec), and will result in a database of 275 Gbyte of pixel data for the 200 f ields of the survey. These data will be processed to produce also a po int source catalogue. As the H alpha survey is an official AAO sky sur vey, both the pixel data and the point source catalogue will be made a vailable to the community as a service facility. We give details of th e digitisation process,archiving of the resulting data and the plans f or dissemination of the database.
