This is an update on my latest 2D hadron rejection optimization results. Compactness__PINCness_1000x1000_bins.pdf

This update is specifically for 1000x1000 bin resolution, which is finer than the previous 100x100 bin resolution results found in HAWC_Update_8_19_16.pdf.

I've uploaded the poster I presented at the Mid-SURE event held at MSU late last month. The presentation seem to go well and I learned a few things to help improve for future presentations.

I was able to replicate John Pretz's results his GH separation code located here:

http://private.hawc-observatory.org/svn/hawc/papers/crab-1yr-performance/plot-making/analysis-start-to-finish/code/expectation.cxx

using the cuts specified here:

http://private.hawc-observatory.org/svn/hawc/papers/crab-1yr-performance/plot-making/cuts/

by using my own version of the code, located here:

http://private.hawc-observatory.org/svn/hawc/sandbox/bentamagne/GHSep/

in the script crossCheck.cc, in which the cuts mentioned above are currently hard-coded in, but I can make revisions if this becomes an issue.

The input file I used is located on the UMD cluster here:

$HAWCROOT/sim/reco/aerie_svn_27754/systematics/best_mc/test_nobroadpulse_10pctlogchargesmearing_0.63qe_25kHzNoise_run4434/sweets/2.63_3.45e-11_1000000_20_1.0/succeeded/2.63_3.45e-11_1000000_20_1.0_combined_rec.root

I have confirmed I am able to reproduce his result of "particles from the crab per day" using the cuts ../cuts/cuts-noghsep-onoffdet-bigbin.txt and ../cuts/cuts-ghsep-onoffdet-bigbin.txt, which directly influence the efficiencies and Q values for each of the fHit bins.

There were two key differences between my own and John's analysis that allowed for this:
    • The cuts files above that John directed me to had an angular binning cut of 4 degrees, supposedly for the purposes of systematics. Whereas my angular binning is dependent on fHit bin.
    • In contrast to my previous versions of my code, John's version used a log parabola energy spectrum for the Crab, whereas I was using the -2.63 power law.

I will confer with John as to which cut files correspond to which efficiency plots given in various talks.

Moving forward is now met with new confidence in confirming that my program does not fundamentally differ from John's established results.
