Description
Measuring collective phenomena in heavy-ion collisions, such as anisotropic flow and its fluctuations, requires an estimate of the collision symmetry plane for different flow harmonics. Each plane's orientation is estimated from the azimuthal distribution of produced particles or from spectators' deflection. Azimuthal non-uniformity in the detector response distorts azimuthal distributions and introduces a bias in the flow measurements. We discuss a correction procedure for the collision symmetry plane estimates and its practical application for a number of ALICE subsystems situated at mid- and forward rapidity.
