This PR:
Simple lambda/photon analysis option:
Adds the possibility to run a simple - yet complete - analysis over photons, lambdas, and antilambdas using the
sigma0buildertask. This mode is intended primarily for QA and cross-checks.Refined selection cuts:
Updates rapidity, pseudorapidity, and z-position selections across all tasks. It is now possible to define selection ranges (min/max values), instead of only absolute thresholds. This enables studies of how the analysis behaves when selecting V0s on different TPC sides.
Additional QA histograms:
Introduces a set of QA histograms to support MC-association sanity checks.
New index tables:
SIGMAINDEX: linksSIGMA0CORES->V0CORESSIGMAMCLABEL: linksSIGMA0MCCORES->MCPARTICLESConfigurable histogram declarations:
Adds configurables to disable unused histograms, reducing memory usage.
More features and minor adjustments will be introduced in a subsequent PR.
