- NRL
- Proton/Interrange
- Mevperdac
- Current cuts pretty restrictive - may want to relax
- Set initial threshold for interrange events at ~200 MeV (actually set at 20% of LEX1 sat.)
- Asym
- Same 4-range data as Mevperdac
- Need to check code for range, order assumptions
- Ped and Intnonlin
- Most corrections applied for BT but not LAT
- Ped temperature corrections
- BT only right now
- Not in offline calib data system; Uses JO/text file
- Monitor requirement early in flight
- Cross Diode Crosstalk
- Code ready for LAT
- Neighboring XTAL Crosstalk
- Important for bkgd rejection
- BT only right now
- Not in offline calib data system; Uses JO/text file
- Code in GR; plan to continue using JO/text file
- Zach discussion with Anders re inclusion in pipeline
- Linear DAC scale correction
- Code ready for LAT
- Ped temperature corrections
- Most corrections applied for BT but not LAT
- GCR peak energy
- Andrey working on this by pulling MC truth out of G4 directly
- GCR.root data used to select appropriate events
- Zach Status
- currently integrating BT xtalk corrections into LAT flight calibrations & recon
- cross-diode crosstalk calculated, needs validation
- neighboring xtal cross talk next
- threshold monitoring works, but needs a little smarter fitting
- currently integrating BT xtalk corrections into LAT flight calibrations & recon

- Latest DGN and MIP filter results: The latest version of the GCRCalib package was included in GR and successfully tested on a background-day sample. It is thus ready to go in L1 P2. The simulation of this background-day sample also included the MIP and DGN filters, that we had not managed to run in Lyon. As you can see from the spectra below (from top to bottom, and left to right: HIP, GFC, DGN, MIP), the proton and He hit rates are ~10 times higher in the DGN filter than in the GFC filter, and the proton hit rate is ~20 higher in the MIP filter than in the GFC filter.
