- Hybrid time sampling (pp): with MAKE_HYBRID_MAPS=true, SLOT_LENGTH_MIN ("fine") maps for the first FINE_WINDOW_MIN minutes of each fill and SLOT_LENGTH_MIN_COARSE ("coarse") maps for the rest. The cutoff is anchored to the fill start, read from optional columns in the discoverResiduals.sh batch file. Per-slot mapMeta.txt in the output.
- MC mode: discoverResiduals.sh --mc [--mc-cycle] searches /alice/sim///// and reads the merged residuals. MC_MODE=true in submitMapCreation.sh (stageSlotsForGrid.py --mc) makes one map per run without the per-TF time cut, since MC residual files carry no time label.
- Post-process: request 1 core (single-threaded macros), shorter c1D/c2D QA PNG names.
- README: hybrid and MC usage, MC examples in the Quickstart.
