4What is it?
5-----------
6
7The module is an object orientated interface to the both the first and second
8Digital Sky Surveys at the ESO-ECF online archive. While the first sky survey
9is 100% complete, the second survey covers 98% of the sky in Red, 45% of the
10sky in Blue and 27% of the sky in the Infra-red.

12Why do it?
13----------
14
15While other, currently undistributed, interfaces to the sky survey are in
16existance, there isn't one generally available. This module, while not as
17feature complete as some other interfaces is a quick and dirty interface
18was fairly easy to code up using bits and pieces of other eSTAR modules,
19see Astro::SIMBAD and Astro::ADS for instance.
