   plotBeamSpotDB
 
   A very simple script to plot the beam spot data stored in condDB
 
   usage: %prog -t <tag name>
   -a, --auth    = AUTH: DB authorization path. online(/nfshome0/popcondev/conddb).
   -b, --batch : Run ROOT in batch mode.
   -c, --create  = CREATE: name for beam spot data file.
   -d, --data    = DATA: input beam spot data file.
   -D, --destDB  = DESTDB: destination DB string. online(oracle://cms_orcon_prod/CMS_COND_31X_BEAMSPOT).
   -i, --initial = INITIAL: First IOV. Options: run number, or run:lumi, eg. \"133200:21\"
   -f, --final   = FINAL: Last IOV. Options: run number, or run:lumi
   -g, --graph : create a TGraphError instead of a TH1 object
   -n, --noplot : Only extract beam spot data, plots are not created..
   -o, --output  = OUTPUT: filename of ROOT file with plots.
   -p, --payload = PAYLOAD: filename of output text file. Combine and splits lumi IOVs.
   -P, --Print : create PNG plots from canvas.
   -s, --suffix = SUFFIX: Suffix will be added to plots filename.
   -t, --tag     = TAG: Database tag name.
   -T, --Time : create plots with time axis.
   -I, --IOVbase = IOVBASE: options: runbase(default), lumibase, timebase
   -w, --wait : Pause script after plotting a new histograms.
   -W, --weighted : Create a weighted result for a range of lumi IOVs, skip lumi IOV combination and splitting.
   -x, --xcrossing = XCROSSING : Bunch crossing number.
