DLB (11/26/06)--Since strong sources may be analyzed with XSPEC, we might want to create XSPEC functions suited for ~GeV range. For example, it would be useful to have a version of the standard power law, broken power law, etc., functions normalized to a GeV. When data at a GeV is fit by functions normalized at 1 keV, the normalization is highly correlated with the other parame parameters
SAE Enhancements From the GSSC beta test
------------------------------------------These are comments compiled by Dave Davis from members of the GLAST Users Committee who participated in the GUC Beta Test in November.
DS9 regions:
gtselect should be able to use ds9 regions for selection
and the SAE tools should recognize ds9 region files.
Proposed method:
Use gtbin to make a projected map
ds9 can then be used to select and exclude regions.
Is there a library to convert .reg files --> DSS regions?
do we need to translate the projected circle --> spherical
circle?
Is this sufficient?
