Working with IPHAS Galactic Plane Data

IPHAS is a survey of the Galactic Plane - see the project pages at http://www.iphas.org.

The Initial Data Release of the northern galactic plane data set has been released through VO protocols, as described in Gonzales-Solares et al, 2008 (see astro-ph). Its contents is described in the IDR Pages.

These pages gives some examples of access to IPHAS data and usage of this in the scientific context.
