Other useful functions during calibration

Skimming local muon triggers only

./DataPrep -f -d 1 -M -i rawPedAndMuon_$RUNNR.root -o raw_muononly_$RUNNR.root 

Skimming local noise triggers only

./DataPrep -f -d 1 -N -i rawPedAndMuonNoise_$RUNNR.root -o raw_pedonly_$RUNNR.root 

Restricting the number of events to be analyzed

For some functions of ./DataPrep an option to limit the running only over a fraction of the events is implemented use -L $NEVTSANA if need be.

Simple HGCROC waveform display

The HGCROC waveforms in our standard output per layer if at all are only displayed as a function of the sample number they have been taken with. However, for instance to further develop it can be very useful to have the waveforms as a function of time in addition.

In order to that either you need calibrated output including the TOA phase corrections. You can run it on a single calibrated file as follows:

./DataPrep -d 1 -E 2 -f -w -i $CALIBRATEDFILE.root -o $OUTPUTFILENAME.root -O $PLOTDIRECTORY -r $RUNLIST 

The most of the options you should have seen before in other steps and they work in the same way. The key option triggering the waveform plotting is -w which doesn't need any further argument. In this particular case no tree-output file will be generated and the histo output file will be named: $OUTPUTFILENAME_hists.root.

Once more most of the histograming is handle by our TileSpectra-class generating all plots for all tiles for two different cases (a) all events/tiles & (b) "triggered" tiles, which in this case means for that specific tile and event a TOA > 0 has to have been registered. The primary routine for this can be found in:

bool Analyses::VisualizeWaveform(void) in Analyses.cc.
