Question

What is the angular resolution of GLAST?

Answer 1

This is the best I could find:

GLAST in orbit will complement the capabilities of the next-generation atmospheric Cherenkov and shower gamma-ray telescopes that are planned, under construction, orbeginning operation, such as ARGO, CANGAROO III, CELESTE, HESS, MAGIC, MILAGRO, STACEE, and VERITAS. These ground-based telescopes detect the Cherenkov light orair-shower particles from cascading interactions of very high-energy gamma rays in the upper atmosphere. They have very large effective collecting areas (>108 cm2), butsmall fields of view (~1°, with the exception of MILAGRO) and limited duty cycles relative to GLAST. GLAST will monitor the whole sky on timescales of hours and willprovide alerts when flaring AGNs are detected. Some of the next-generation Cherenkov telescopes will have sensitivities extending down to 50ÊGeV and below, providing abroad useful range of overlap with GLAST
