DataSubselector (gtselect) will be extended to allow for energy-dependent cuts using the DSS keyword scheme that Yasushi Ikebe devised. Tom will do this. The motivation was the GUC beta-test feedback regarding data selection of pulsar analysis. The discussion regarding the DSS keywords was related to the question of how gtlikelihood might recognize if it is handed a file that has had an energy-dependent cut applied, and therefore cannot analyze.
Here is the link to Yasushi's page describing how to do it. http://glast.gsfc.nasa.gov/ssc/dev/fits_def/dss_keywords.html
8. DS9 selection regions
Chris will investigate the possibility of getting the Center for Astrophysics to implement GLAST-specific changes to DS9, in particular selections of ROIs with correct spherical geometry. This will be coordinated through Bill Pence who has regular interactions with the group that maintains DS9.
