Framework

• [Presentation] First presentation about the computational framework. Introduction to the event displays.

Implementing Python chain and reducing cluster splitting

• [Presentation] Implementation of full Stage2 reconstruction chain with Python. First results on reducing cluster splitting.
• [Presentation] Additional results on cluster splitting reduction, including alternative methods to the bye-splits algorithm.

Seeding in (U,V) coordinates

• [Presentation] First study on using wafer/cell (u/v) coordinates to perform the seeding, starting from ROIs. First time algorithm performance was measured using the full ROI chain.
• [Presentation] Addressing comments of previous presentation; first time O(thousands) of 0PU events are used for performance evaluation of both the hexagonal seeding (100% efficiency) and the full coarse seeding chain.

Cluster size studies

• [Presentation] First presentation on the cluster size studies, describing the goal and general procedure. Some very preliminary results on 0PU samples were also included.
• [Presentation] Description of workflow for the clustering size studies, with a few preliminary results for both 0 and 200 PU.
• [Presentation] Update on 3D Cluster Size Optimization in the CMS HGCAL TPG System

HGCAL front-end and back-end mapping

• [Presentation] First presentation on front-end mapping using Pedro's geometry file. Geometry v14.3 has been used, now moved to v15.3.
• [Presentation] Front-end to back-end mapping checks using the files from Andy's repo. Stage-1 to channels mapping is also included. Used geometry v15.3.

Stage-2 back-end emulator

• [Presentation] Status of the standalone emulator and next steps.
