// plotdb.C
// ========
//
// This macro is used to read quality parameters from the DB and plot them.
// 
// The parameters are from the following files:
// calib*.root:mean conversion factor, mean arrival time, rms arrival time
// (each parameter for inner and outer camera)
// signal*.root: mean pedestal rms (for inner and outer camera)
// star*.root: PSF, # of Muons, Effective OnTime, Muon rate,
// Ratio MC/Data(MuonSize) and mean number of islands
// 
// In the DB these values are stored in the tables Calibration and Star.
// 
// Usage:
//   .x plotdb.C   --> all values in the DB are plotted
// You can chose are certain period:
//   .x plotdb.C(25)   --> all values from period 25 are plotted
// or a time period from a certain date to a certain date
//   .x plotdb.C("2004-11-14 00:00:00", "2005-02-28 00:00:00")
//  --> all values from 14.11.2004 0h to 28.2.2005 0h are plotted
// or all data, but with dataset data highlighted
//   .x plotdb.C("dataset.txt")
//  --> the sequences defined in dataset.txt are highlighted (blue:on, red:off)
//  --> You can also add a dataset-name as last argument to one of the
//      calls above
//
// Make sure, that database and password are corretly set in a resource
// file called sql.rc and the resource file is found.
