SIGMA - GRANAT

Welcome to the SIGMA server of the CESR
=======================================

SIGMA space telescope is devoted entirely to the high energy astronomy. 

Scientific objectives of the mission are :

* link:sky[Imaging ot the sky] in the energy range 35 keV to 1.3 MeV.
* Temporal and spectral analysis of localised link:sources[gamma-ray sources] 
in the same energy range.
* Temporal and spectral analysis of gamma-ray bursts in the energy range 200 keV
to 15 MeV.

The link:telescope[] has been constructed by two French laboratories :

* The link:http://www.cesr.fr[(CESR-CNRS/UPS)] in Toulouse,

* The link:http://dphs10.saclay.cea.fr/Plaquette/Sap/sapf.html[(SAp/DAPNIA/DSM/CEA)] in Saclay,

Both under contract to the link:http://www.cnes.fr[CNES]
