Analysis

The analysis results from this paper, including the plots, are reproducible.

If you have installed the joint-crab bundle as it is described in the README, you can type in the terminal the following commands to reproduce the analysis and figures. You may choose to perform the whole analysis with a single command or do it in a step-by-step basis.

All steps in a sigle command

$ ./make.py all

Step-by-step

1- Let's clean eventual previous results produced.

$ ./make.py clean

2- We perform the analysis in a procedural way.

$ ./make.py maps
$ ./make.py extract-spectra
$ ./make.py fit-spectra
$ ./make.py fit-systematics
$ ./make.py fit-errorbands

3- Then we gather the results in tables.

$ ./make.py summary-data
$ ./make.py summary-results

• Table 1: results/summary/data.md | results/summary/data.tex
• Table 2: results/summary/results.md | results/summary/results.tex

4- Finally, let's produce the plots.

$ ./make.py plot-counts

• Fig. 1: results/figures/counts_spectra.png | results/figures/counts_spectra.pdf

$ ./make.py plot-seds

• Fig. 2: results/figures/crab_sed_fit.png | results/figures/crab_sed_fit.pdf

$ ./make.py plot-errorbands

• Fig. 4: results/figures/errorband_sed_veritas.png | results/figures/errorband_sed_veritas.pdf

$ ./make.py plot-contours

• Fig. 3: results/figures/contours.png | results/figures/contours.pdf
