12 June 2020

Experiments on analysis:

1. Don't delete any sources. You can do this by commenting out the options under delete_sources and add an empty list so it just says delete_sources: [].
2. Free everything by setting the minmax_ts min ts value to 0 and the distance to something large (I think anything larger than 20 will do).
3. Fix everything (i.e. free_sources: [] .
4. Play around with changing the distance parameter instead of or in addition to the min ts.

11 June 2020

9:30 Call with Reshmi

• Run a complete lightcurve: time bin TBD

  • Goal: Next Thursday

• Prepare slides for next Wednesday: general: slide 1: fermi, blazars

  • Gamma-ray flux distribution of blazars, variability, light curves, inspo. from the stochastic process paper

2:00 Call with Ari

• Review output files from updated pipeline config file. Looks pretty similar. Spike in residual map sigma histogram is still there even after the TS cut. The histogram is more centered and smoother though.

  • Spike indicates that there are some parts of the analysis that are not converging.
• Apply a more extreme TS cut: >1000 and re-run analysis
• ls -hlt == check on when files were last updated

9 June 2020

• Rerun FermiPy analysis with the new config file: update TS parameters

  • TS min: 25 to 100
• Read paper: Characterizing the Gamma-Ray Variability of the Brightest Flat Spectrum Radio Quasars Observed with the Fermi-LAT
• Write Shut Down Stem meeting agenda with Colin & prepare for the meeting

8 June 2020

• Finish slides

• 1:00 Call with Ari

• Discuss FermiPy analysis outputs

• 2:00 Group Meeting
  • ShutDownStem and Particles for Justice: Wednesday - use this time to meet and discuss anti-racism in our group
  • Community code of conduct - inspired by Astropy
  • Sharing education resources. We must have the uncomfortable conversations and make an ongoing effort of anti-racism within our group and other institutions we occupy.
  • Working with Colin and Deivid on organizing the meeting Wed. and the plan going forward.

4:15 Call with Ari

• eog : use to open all output graphs in 1ES2344

  Issues: Residual maps have negative excess blob (blue) which indicates that we need to tweak the sources in the analysis
  • Possible solution: increase TSmin from 25 to 100, extended sources might be an issue (not a point source, fermipy could get confused with that data)
  • TS edits are in hard code

5 June 2020

• Check on analysis from yesterday: failed

  • "CFITSIO ERROR 107: tried to move past end of file"
  • fermipy.log has same output as nohup.out
  • Solution: time range begins too early: change tmin=234316801 to tmin>=239557417.494176 in config file
  • Delete all old output files (avoid corruption): rm -r 1ES2344

• Begin slides for on the distribution of fluxes of gamma-ray blazars: hints for a stochastic process?
  

  • Define deterministic vs stochastic. Unpack the SDE. Explain analysis and conclusions made.

4 June 2020

9am meeting with Reshmi and Elisa

• Default (monthly) bins on light curves. Then do 3 day bins.

• Date range: Fermi mission start date April 2020

• April 2020 - stochastic processes paper: plots of dN/df are interesting analyses on six of the strongest quasars. Try to run these plots for these fermi sources. Run their analysis, apply modeling.

  • Try to extend the plots to include both fermi and veritas flux.

  • Integrated flux, independent of time. Flux in bins. Counts per bin. One step further > dn/df plots

• Next week’s goal: ramp up on fermi analysis. Fermi light curve one first source: flux distribution, dn/df plot. Geibles 2004 paper.

• Flux vs time plot: how to convert into a fits file > Terek could know.

• Slides for paper: data used, analysis used, conclusions made.

Start time: 234316801.000 (MET) = 2008Jun05

End Time: 607392005.000 (MET) = 2020Apr01

Configuring analysis:

The original prefix is "3C279" which is for the quasar. So if I am doing analysis on 1ES 2344+514 the prefix should be "1ES2344"

3 June 2020

Morning:

• Reviewing Unix/Linux tutorials > continuing working on familiarizing within tehanu

• Following FermiPy configuration steps

  • Question: how do you determine the start/stop time of the analysis?

    • Asked Ari > we will ask in group meeting

    • I assume there is a time range picked for the GeV -TeV project

• Writing short bullet points for my research interests. I sent them to Kayla for the website.

• Using 4FGLto match the source names with the 4FGL names

  • I need either the name or the coordinates for the config file.

  • Question: If I cannot find the 4FGL name (from TeVCat), does that mean that it is not in the catalog?
