| - | The calibration procedure starts with a detmap file. Such a file exists for each quad. Each file is a plain text list of the offset and gain of each channel of the quad respectively. The channels are seperated by new lines. The order of the channels is in the the daq order (i.e the order they arrive at the digitizer, remember Q1 is different). The naming scheme of the files is important for the rest of the scripts to work; current convention is **detmap_Q1.txt**, where the 1 could be replaced by any quad number. | + | The calibration procedure starts with a detmap file.
