Most of the data files are related to various BDTs (Boosted Decision Trees) that were used while studying the ECal's veto performance. Only two of the files have been copied from the legacy submodule into ldmx-sw v4.

You can still download the legacy data files from the archived submodule LDMX-Software/Ecal. Putting them in this directory will mean they will be installed along side the current BDT model (gabrielle) and the cell locations text file (cellxy).
