This short document describes all the settings for BET EF for Colima volcano that were decided BEFORE the beginning of the Colima exercise. The settings were decided by Laura Sandri and Dmitri Rouwet, stemming from 2 reports that we had received from Raul Arambula and Gabriel Reyes of UNAM. The last section of the document shows some results and a short collection of figures displaying the output from BET_EF for the first phase of the Colima exercise.
