• continued my work on the SED model for 1215 with major success. Have only a little left to alter for a final fit which this is getting close to.
• read through the decadal survey from VERITAS, focusing on what has relevance to my work. Was very long and complicated so I will need to go back this resource later.

• Started to focus on the material I am going to present on Tuesday to the REU group at the REU lunch
  • Want to be more specific with the scientific theory
  • inverse Compton scattering
  • photon reabsorption
  • leptonic vs hadronic modeling
• ran into hardware issues, my computer would not let me use the trackpad or keyboard
  • went to the apple store and a new computer isn't available for a couple of months...

• my computer still had issues today but they were resolved by restarting my computer 4 times and leaving it to sit unplugged and shut down for 20 minutes
• beginning the creation of the slides for the presentation Tuesday.
  • will likely have this as something to continue working on over the break weekend (July 4th)

• finalized and presented presentation on Blazar physics to REU group

• gave up on my computer in favor of the spare
• beginning VEGAS analysis of 1ES 1215+303 for 2021
  • running a crab analysis again to make sure I can do the steps properly
  • will be applying time cuts in the method Leela recommends from thier own experience with VEGAS
• source has only three runs in 2021 which are of acceptable quality (only one other run of 'D' quality) to be included in the analysis (time cuts noted)
  • 97993
    • time cut from 10.25 - 11 min
  • 98127
  • 98346
    • time cut from 10.5 - 11.5 min and
    • time cut from 17 - 20.5 min (both)
• hope to have spectrum, skymap, and lightcurve for this source by the end of the week
• successfully complete a trial crab analysis

• set up and began VEGAS analysis of 1ES1215+303
  • downloaded the appropriate runs
  • applied correct time cuts
  • began stages 1-5
• started work on the final presentation/paper

• Meet with Dr. Muhkerjee to discuss progress and upcoming meeting with the group from CalPoly
  
  • need to prepare slides for group meeting Thursday as well as Friday's meeting
    • Fridays slides: Blazar physics and accelerated jets / SED modeling

• day off - trip to BNL

• Ran stage6 and began interpretation of output
• using Massimo's plotting code for stage6, got significance map and Excess counts map for 121
  • need to learn more about what these are, the science behind them, and create slides about them
  • understand generally:
    • significance map : source - background / width of source (?)
    • excess counts : counts which are above the background noise (source - background)
  • need to get to the point where I understand how they can be useful to analysis
• Want to plot flux with archival data I have been plotting already

• have preliminary slides created for meeting with CalPoly, but need to flesh them out a little more, especially with respect to the main focus which should be SED modeling
• analysis of 1215+303 was insignificant and may try to rerun analysis with the inclusion of 1218+304
  • new runlist needed for this
  • will start with 2021 but may go back to 2020 if I have time
  • loggen system is down so will have to start this tomorrow
  • stages 1-5 should be normal but need to include some options on the config for stage 6:
    • S6A _TestPositionRA=184.467
    • S6A _TestPositionDEC=30.1168
    • S6A _UserDefinedExclusionList="exclude1218.txt"
  • must create this file exclude1218.txt:
    • 185.341428 30.176989 0.3
    • 1ES1218+304
• this will hopefully produce some interesting data, but must consider whether any of the runs include non-low state data
• the future of this analysis:
  • no time for but would be nice to have a fermi analysis of this source for 2021
  • inclusion of multiwavelength data for SED fitting
    • I know where to find X-ray data
    • nothing else
  • SED fitting for new data?

• Started new analysis for 1215 with 1218 runs included
• new runlist:

  • 20210117 97597 97593 97593 97593 97593

• only one new time cut:
  • 97597
    • time cut from 26.5 - 30 min
• Finished slides for meeting tomorrow with CalPoly

• analysis finished running overnight but ran into issues before I could run stage 6, will retry Monday
• meeting with CalPoly was successful
  • journal club formed. meeting next Tuesday
    • Read Marcus' Paper on Hadronic and Leptonic Blazar Modeling (https://arxiv.org/abs/1304.0605)
    • Read Matteo's Paper on the same Hadronic and Leptonic Processes (https://arxiv.org/abs/2012.13302)
  • next meeting is next Thursday since Friday doesn't work.

• Returned spare computer to Amy today
• Restarted analysis of 2015+2018 runs
  • applied all time cuts properly.
• also started analysis for Pablo since he was unable to download runs on his terminal.
  • may just go ahead and finish the analysis for him on my computer since its only 3 runs and shouldn't take too long to complete.
• read through the papers for tomorrows meeting with CalPoly
