ECA_CONTROL.DAT contains the CECA titles bank which controls the basic ECA parameters. Aside from the choice of calibration type (which you've already made via mnemonics), there are only a couple you generally ever need to bother with. First is whether to output the short or long form of the summary file (word 20). Set this to 1 for the short form or 2 (default) for the long form. Second is whether the linear charge fits should be forced through their measured pedestal (word 21). Set this to 1 for an unconstrained fit and 2 (default) to force it through the pedestal. If the latter is chosen, you must obviously run the pedestal calibration first and then load the resulting titles file in your ECA_READ.CMD (see the commented-out line in the example file).
