Unzip the zip-files (including the *domcal.zip file) of a time-resolution run and execute the following script:
coinc-kdh.py $DATADIR/SWEDAQ01_run0000333_TimeResolution-ATWD1-15000Hz.hit  (no line break here!!!!!) $DATADIR/SWEDAQ01_run0000333_TimeResolution-ATWD1-15000Hz.tcal $DATADIR/domcal*xml
The output is a ROOT file 'coinc.root'. Check the histograms (one for each DOM) in a ROOT session and fit them. The standard deviation should be reported at the end of the FAT.
