research on 4 events
Reading and preparing motivation slides for REU talk
Compare weight factor for the detected events (2 HESS and 2 MAGIC), versus our VERITAS list below.
For the following list of VERITAS observations:
Find zenith for each run (
https://veritasm.sao.arizona.edu/DQM/loggen.html
)
Use zenith to get energy threshold (E_th) (
https://veritas.sao.arizona.edu/wiki/Performance_Paper#Zenith_angle_vs._Energy_threshold
)
Plug in E_th to weight factor equation (W = e^tau/t_delay, where tau=tau(z, E_th) ) Use gammapy to get this e^tau. Use Gilmore EBL model.

Jamil
Worked with gammapy tutorials. Did HESS survey map. Is map telescope pointing, or event counts?
Can check this HESS map for plotting different scale (linear vs log)
Use the 4 pointing files from gammapy to simulate the Crab.
Massimo will reach out to gammapy contact to get more pointing files.
Daniela
Worked on Blazars slides for presentation.
Will work on
GeV
TeV cutoff. Has a spreadsheet for runs to analyze and has begun downloading.
Qi gave some feedback on slides.
Qi and Elisa will pick one priority source for Daniela to work on. Next call with Elisa next week.
Laurel
Working on testing the GUI. Tested power supply.
Might need a different connection for library to communicate with power supply.
Marcel Grossman Meeting Practice Talk
9am Thursday July 1.
Talks every two weeks
Particle Acceleration and Shocks: Organized by Reshmi + Felix Ahoronian

Optics work
Finish S1 alignment
MPES debugging and alignment to constrain panel motion (by freezing Rx, Ry and Tz motions)
P2 and S2 first order correction to be measured
SPIE proceeding  technical (Camera), observation (Mkr421) and optics(?). "Technical and Scientific Performance of the pSCT".
ICRC
Author list to be compiled in format for submission(Thanks Reshmi!)
Tehanu cluster
Need to estimate RAM needed for VEGAS jobs. Email Alisha Chromey + Jodi Christianson for advice.
