Data Quality

Raw data came from AMS in form of Blocks, binary files containing the AMS encoded informations. Block files a come 1 per minute. We promptly decode, reconstruct and analyze this data in order to have a fast quality check. The decoded informations are:

  • AMI Monitor: in order to have meaningful data is important to have the Tracker in stable temperature condition (a rapid increase temperature will give a raise in the Tracker event size!)
  • Decoding program: this program does all the job. It takes a block, decodes it, reconstructs the track and prepares histograms.
  • MonitorUI: user interface to the monitoring and calibration files.

You can reach this programs from the data quality directory from every PC in the POCC. You have to logon with the tracker user (no password required) and go to the ~/TrackerUser/Monitor directory.
