Intro:
- missing information for FWDCKV everywhere, FWDLNX in the ebeam-only
- fill the beam only numbers for the production progress

Tony:
- gone to 10*(1+xi^3) —> getting much more HICS photons important for the trident process where pairs are produced
- 600 positrons per BX for JETI40 at 3 um spot-size !
- table is updated —> take much longer since the calculation is very long
- add the BPPP on the same plot as the top 
- for phase2 we should go down only to ~8 um
- try to clean the dirs, also there was a problem on NAF up to yesterday
- move all things which are wrong/outdated to old/ directory
- Daniel: what is the summation limit for the pair production case?
    - Tony goes up to 10^-8 of the total
    - should also behave as ~xi^3 —> Tony will validate

Sasha:
- 5,8 and 50 um point is regenerated with the new IP CKV+LANEX geometry
- fixed a few problems in the cluster
- some improvements with speeding the code
- should move the stave a few mm up/down to avoid the carbon space frame to be in the middle of the stave
- Ruth/John, Arka and Louis will process Sasha’s new files for the “very old” signal files from Tony (not the provisional!)  for 5, 8 and 50 um. we need mostly to look at the levels of backgrounds and the vertices etc.

Kyle:
- updates on the x-section
- working on radiation maps

Maryna:
- added 5 um (provisional)
- added the minimum energy cut and all points are much more aligned now (Ne vs Ng)
- add the acceptance curve vs E

Louis:
- working code —> will share with TAU
- looking at particles coming to all faces of the calo
- invert the colours of the 2D plots?
