GILDAS is a collection of  software oriented toward (sub-)millimeter radioastronomical applications (either single-dish or interferometer) created and maintained by IRAM (Institute de Radioastronomie Millimétrique in Grenoble, France.


Guildas is installed on all linux machines at the institute. To use the software you need to load two modules:

module load Intel_parallel_studio/2019/4.070

module load gildas/sep19a
