Next: Observations and Analysis Up: The Second EGRET Catalog Previous: The Second EGRET Catalog . ... The first EGRET catalog ([ Fichtel et al. 1994b ]) covered Phase 1 of the Compton Gamma Ray Observatory (CGRO) viewing program which began shortly after launch of the observatory on 1991 April 5 and ended on 1992 November 17. ... No additional solar flares were seen during Phase 2; therefore, the first EGRET catalog summary has not been updated in the present work. ...

The A TNF S pectral A nalysis P ackage is a new software package that has been developed within the ATNF, to reduce single-dish, single-pointing spectral line observations. ASAP is now used for single-dish data from ATNF instruments and should be able to read data from any telescope if the data can be written in the "sdfits" format. ... The c++ code makes extensive used of the casa libraries (the package formerly known as aips++). ... A binary version for Fedora Linux should be available shortly. ...
