Attaching some scripts that help processing the effective volumes. This is an extension of what Brian Clark did in a previous post (http://radiorm.physics.ohio-state.edu/elog/How-To/27)

There are 4 files attached:

- veff_aeff2.C and veff_aeff2.mk. veff_aeff2.C produces Veff_des$1.txt ($1 can be A or B or C). This file contains the following columns: energy, veff, veff_error, veff1 (PA), veff2 (LPDA), veff3 (bicone), respectively. However, the energies are not sorted.

-veff.sh: this bash executable runs veff_aeff2.C for all (that's what the "*" in the executable is for) the root output files, for a given design (A, B, C). You need to modify the location of your output files, though. Run like "./veff.sh A", which will execute veff_aeff2.C and produce the veff text files. Do the same for B or C.

-make_plot.py: takes Veff_des$1.txt, sorts energies out, plots the effective volumes vs. energies, and produces a csv file containing the veffs (just for the sake of copying and pastting on the spreadsheets). Run like "pyhton make_plot.py".
