18// Modified version of AliAnalysisTaskCheckCascade.cxx.
19// This is a 'hybrid' output version, in that it uses a classic TTree
20// ROOT object to store the candidates, plus a couple of histograms filled on
21// a per-event basis for storing variables too numerous to put in a tree.
22//
23// --- Adapted to look for lambdas as well, using code from
24// AliAnalysisTaskCheckPerformanceStrange.cxx
25//
26// --- Algorithm Description
27// 1. Loop over primaries in stack to acquire generated charged Xi
28// 2. Loop over stack to find Cascades, fill TH3Fs "PrimRawPt"s for Efficiency
29// 3. Perform Physics Selection
30// 4. Perform Primary Vertex |z|<10cm selection
31// 5. Perform Primary Vertex NoTPCOnly vertexing selection (>0 contrib.)
32// 6. Perform Pileup Rejection
33// 7. Analysis Loops:
34// 7a. Fill TH3Fs "PrimAnalysisPt" for control purposes only
35//
36// Please Report Any Bugs!
