Attached are instructions and scripts for carrying out a parameter space scan with ShelfMC, the simulation package for the ARIANNA detector.

Because some of the plotted outputs looked like colored stripes and did not offer any insight into how effective volume changed with some variables, I made some changes to the simulation and plotting scripts so that different maximum, minimum, and increment values can be chosen for each variable. Now rather than having fixed, hard-coded values for all variables, the parameter space scan and plotting is more flexible for use with variable inputs.
