A quadratic parametrization of dust-scattered UV light, fitted to GALEX data at the North Galactic Pole, yields an isotropic background of 267 ± 7 photon units and is consistent with the Astrodust dust model.

abstract
GNU Data Language (GDL) is an open-source interpreted language aimed at numerical data analysis and visualisation. It is a free implementation of the Interactive Data Language (IDL) widely used in Astronomy. GDL has a full syntax compatibility with IDL, and includes a large set of library routines targeting advanced matrix manipulation, plotting, time-series and image analysis, mapping, and data input/output including numerous scientific data formats. We will present the current status of the project, the key accomplishments, and the weaknesses - areas where contributions are welcome !

Modeling the Cosmic Ultraviolet Background at the North Galactic Pole
A quadratic parametrization of dust-scattered UV light, fitted to GALEX data at the North Galactic Pole, yields an isotropic background of 267 ± 7 photon units and is consistent with the Astrodust dust model.
