2 // Base macro for submitting muon Resolution analysis.
4 // In case it is not run with full aliroot, it needs the following libraries:
9 // - libANALYSISalice.so
12 // - libProofPlayer.so
14 // - libRAWDatabase.so
18 // - libMUONmapping.so
20 // - libMUONgeometry.so
21 // - libMUONtrigger.so
27 // - libPWG3muondep.so
29 // It also needs to load magnetic field, mapping, geometry (+alignment), and reconstruction parameters from the OCDB
31 // The task reads ESDs
32 // Intermediate results are stored in a file chamberResolution_step<#step>.root
33 // Final results are stored in the file results.root
