SIGMA - GRANAT

SIGMA scientific observations for year 1991
===========================================


For each month are mentionned :

* the mode of observation used with the telescope :
** SI for spectral-imaging mode,
** VI for variability-imaging mode, 
** PH for photon-photon mode and 
** VR for fast-variability mode), 
* the source studied, 
* the acquisition time of images and 
* the coordinates of the SIGMA telescope pointing (alpha 1950 and delta 1950)
