9 // AliTPCComposedCorrection class //
11 // This class is creating a correction that is composed out of smaller //
13 // There are two ways the sub-corrections can be combined into this one: //
14 // 1. kParallel: All corrections are applied at the given position x and //
15 // the dx terms are summed up (this commutes). //
16 // 2. kQueue: The corrections are called in order. The first one at the //
17 // given position x resulting in dx1, the second one is called at //
18 // the corrected position (x+dx1) resulting in dx2, the third one //
19 // is then called at position (x+dx1+dx2) and so forth. dx=dx1+dx2+... //
21 // For the inverse of the correction this is taken into account by reversing //
22 // the order the corrections are applied in the kQueue case (no issue for //
25 // date: 27/04/2010 //
