Digitisation, Archiving and Dissemination of the 275 Gbytes of the AAO/UKST Halpha Survey Data

Abstract

We plan to digitise the AAO/UKST Halpha survey of the Southern sky using the SuperCOSMOS facility at the Royal Observatory Edinburgh. The digitisation 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 fields of the survey. These data will be processed to produce also a point source catalogue. As the Halpha survey is an official AAO sky survey, both the pixel data and the point source catalogue will be made available to the community as a service facility. We give details of the digitisation process, archiving of the resulting data and the plans for dissemination of the database.
