7AliTRDCalibPadStatus - pad status calibration
8
9This program reads the DAQ data files passed as argument using the monitoring library.
10
11It fills a TRD calib object AliTRDCalibPadStatus and write it in a local file trdPedestal.root before
12exporting it to the file exchange server.
13
14Messages on stdout are exported to DAQ log system.
