20 // TRD tracking resolution //
22 // The class performs resolution and residual studies
23 // of the TRD tracks for the following quantities :
24 // - spatial position (y, [z])
25 // - angular (phi) tracklet
26 // - momentum at the track level
28 // The class has to be used for regular detector performance checks using the official macros:
29 // - $ALICE_ROOT/TRD/qaRec/run.C
30 // - $ALICE_ROOT/TRD/qaRec/makeResults.C
32 // For stand alone usage please refer to the following example:
