1 Background sources update
Toby Burnett Analysis Meeting 4/11/05 - T. Burnett

2 Analysis Meeting 4/11/05 - T. Burnett
Review Julie’s pointing history Proper slewing, Sun avoidance New exposure/background support in Gleam. [GlastRelease v6r6] S/C height calculated properly Table lookup for geomagnetic quantities CRflux package modified to use this rather than Palestine Analysis Meeting 4/11/05 - T. Burnett

3 CRflux status: unchanged
Uh-oh! No azimuthal variation Analysis Meeting 4/11/05 - T. Burnett

4 Analysis Meeting 4/11/05 - T. Burnett
Rates vs time, 2 orbits p p e+ He e- e- e+ Analysis Meeting 4/11/05 - T. Burnett

5 Analysis Meeting 4/11/05 - T. Burnett
Albedo Gamma source APOD 31 March 05 Analysis Meeting 4/11/05 - T. Burnett

6 Analysis Meeting 4/11/05 - T. Burnett
Overall status No check on overall rates yet. This is not the same code which was used to generate the plots in Mizuno et al. No E-W effect Altitude effect on albedo? Dirk’s model not yet ready: until then we will use the old albedo_gamma. Next: compare these fluxes with “PDR” version. Analysis Meeting 4/11/05 - T. Burnett
