/**
 * This macro can run on the output root file from SyncO2O and produce
 * a histogram showing the digis, digis with masking and number of
 * detIds with HV off. <br>
 * The digis with masking should remain always at a stable level during
 * a run and go to zero when the tracker HV is off. <br>
 * In contrast the digis will go up when the HV is being turned off. <br>
 * The increase in modules with HV off (provided a sufficient reduction
 * is used) will be a straigth line going up and will begin when the
 * off command is given to the modules from DCS.
