8aa336b1 20/// \class AliMUONQAChecker
21///
f587a77d 22/// Implementation of AliQACheckerBase for MCH and MTR
8aa336b1 23///
f587a77d 24/// For the moment we only implement the checking of raw data QA for the tracker
25/// by looking at the occupancy at the manu level.
26/// We count the number of manus above a given occupancy threshold, and
27/// depending on that number, the resulting QA flag is warning, error or fatal.
28/// (there's no "info" type in this case).
