//
// fillsignal.C
// ============
//
// This macro is used to read the calibration-/callisto-output files
// signal00000.root.
//
// From this file the Mean PedRms for the inner and outer camera is extracted.
//
// Usage:
//   .x fillsignal.C("/data/MAGIC/Period014/signal00000.root", kTRUE)
//
// The second argument is the 'dummy-mode'. If it is kTRUE dummy-mode is
// switched on and nothing will be written into the database. This is usefull
// for tests.
//
// The macro can also be run without ACLiC but this is a lot slower...
//
// Remark: Running it from the commandline looks like this:
//   root -q -l -b fillsignal.C+\(\"filename\"\,kFALSE\) 2>&1 | tee fillsignal.log
//
// Make sure, that database and password are corretly set in a resource
// file called sql.rc and the resource file is found.
//
// Returns 0 in case of failure and 1 in case of success.
//
