The trimbits and calibration files

In order to be able to properly operate your detector you need a directory where the trimbit files (needed to set the detector settings and eventually equalize the individual channel thresholds) which in the following will be named trimdir and a directory where the calibration files (needed to convert the threshold energy in DAC units) are stored which in the following will be named caldir. trimdir and caldir can even be the same directory, and an example of it is given in the software package by the example directory trimbits.
Since these directories are customized by producing trimbit files and calibration for each detector, make sure not to overwrite yours every time you upgrade the software.

trimdir should contain three subdirectories standard, fast and highgain containing respectively the trimfiles standard.trim, fast.trim and highgain.trim which contain the correct voltage settings for the detector although all the individual channel thresholds set to 0. The original files contained in the package should be used, infact in case of error the detector would not recognize the correct settings.
The default trimbit files for each file will be stored in the directory according to the settings with the name noise.snxxx where xxx is the module serial number.

caldir should contain three subdirectories standard, fast and highgain containing respectively the trimfiles standard.cal, fast.cal and highgain.cal which contain an average calibration of the modules for the diffrent settings. However this can different from the correct one for each individual module even of several kev and therefore it is very important to perform an energy calibration on a module basis (see section ).
The default calibration files for each file will be stored in the directory according to the settings with the name calibration.snxxx where xxx is the module serial number.
