review/update PackedCandidate packedHits_ and packedLayers_ to cover phase-2 IT tracker (etc) #43474

Open slava77 opened 12 months ago

slava77 commented 12 months ago

@AlexDeMoor noted that the truncation/packing done in ParckedCandidate::setHits may in general be insufficient https://github.com/cms-sw/cmssw/blob/27bec5ff620bde58ac4a2a2812a545e881c47117/DataFormats/PatCandidates/interface/PackedCandidate.h#L623-L647

Notably, pixel layer/hits are truncated at 7, which is insufficient for phase-2 IT.

The strips are truncated at 31, which should be OK for the current SST or for OT.

Looking at a typical phase-2 geometry in the tkLayout page (here for geometry T32, layout OT800_IT615), looks like at the peak there's about 16 Inner Tracker hits and 10 crossed layers
