16// AlidNdPtCorrection class:
17//
18// a. functionality:
19// - applies corrections on dNdPt spectra
20// - fills corrected dNdPt histograms
21// - fills correction control histograms
22//
23// b. data members:
24// - dNdPt spectra before and after correction procedure
25// - control histograms
26// - correction matrices (must be loaded)
