MiniRun5 era: Known issues and WIP features

Directly related to MR5 samples

• In the light simulation, signal only appear in channel 4-31 (https://indico.fnal.gov/event/64244/contributions/288618/attachments/176632/240131/240409_simcalib_MR5_issue.pdf)
• In the light simulation, a single segment can be backtracked to multiple trigger and true events
• Add light backtracking info for light hits
• [Temporary fix available] In larnd-sim, the true segments are not updated with “quenching” and “drifting”
• ndlar_flow would crash if you don’t pass all segments
• [Fixed in a feature branch] In MR5 beta 1, the x and z are flipped in the “segments” dataset (https://github.com/DUNE/larnd-sim/pull/204)
• [Origin of the issue found by Jaafar; the pixel pitch in the layout file will be updated; the larndsim function will be updated]The y position has a increasing shift from bottom with respect to its corresponded true segments (https://indico.fnal.gov/event/64244/contributions/288617/attachments/176623/240114/minirun5_spatial_offset___2x2_simulation_calibration___8april2024.pdf, https://indico.fnal.gov/event/64542/contributions/290387/attachments/177430/241559/20240429_GeometryBugFix.pdf)
• In ndlar_flow use a non physical value for filling the backtracking values (https://github.com/DUNE/ndlar_flow/issues/115)
• Propagate “event_id” in the backtracking information in ndlar_flow (https://github.com/DUNE/ndlar_flow/issues/115)
• [Fixed] Light gain applied as for channel 4-9 because of the yaml parser (https://github.com/DUNE/ndlar_flow/issues/114)
• [Implemented] Flash reconstruction in ndlar_flow

A little bit beyond MR5 samples

• Reproducibility: set the appropriate random seeds to control the randomness (Important for detector systematics) (https://github.com/DUNE/larnd-sim/issues/125)
• Fix threshold triggering for LRS and trigger forwarding to pacman
• The LUT has redundant size (~60% 0’s)
• [Fixed, not merged to “develop”] propagate the vertex information to “mc_truth/interactions” (https://github.com/DUNE/ndlar_flow/issues/108)
• Missing readout hits from some io_groups for mpvmpr samples
• [Stephen has developed it during the 2024 May workshop; PR to be checked and merged]Develop an inclusive event builder for beam and non-beam events
• New response files
• Optimize hit merging where it shows a second peak in Q and E (https://github.com/DUNE/ndlar_flow/issues/111)
• Hit merging becomes very slow for larger number of hits (observed with mpvmpr, optimization needed)
• Provide options to load charge and light geometry separately (https://github.com/DUNE/ndlar_flow/issues/102)
