FGS reports about the status of the WT8 activities, especially after the SST Workshop held in Cagliari in May 2024.

2 Status of the single-telescope high-level simulations

Speakers: Dr Sabrina Einecke (University of Adelaide), Dr Simon Lee (University of Adelaide)

SL has run some preliminary simulations, changing some parameters to what was agreed in previous discussions. There are some of them that require attention, for which there is a discussion underway.

• RW explains that some parameters could indeed affect the comparison between the simulations and the real data, but for the CDR their update is not strictly required. Other parameters (e.g., the camera window transmission) are being updated now, with the relative documentation being written. For these parameters, a valid strategy for the CDR is to adopt pessimistic versions in the simulations to verify that the system stays within the CTA requirements.
• SE asks how the WT8 wants to track the status of each parameter. FGS and SL agree on a shared Drive Excel document (in the spirit of what was done for Prod6 parameters). RW suggests to copy the actual Prod6 spreadsheet; there is also a GitLab repository with several useful documents and open issues, that may be rebuilt for the current user case.

3 Status of the SST prototype high-level simulations

Speakers: Dr Sabrina Einecke (University of Adelaide), Dr Simon Lee (University of Adelaide)

About the SST prototype simulations, FGS suggests to postpone them to when the CDR documents will be almost ready. RW, SE and SL agree, unless some hard deadline must be set for this activity.

4 Document for engineering simulations

Speakers: Dr Gianluca Giavitto (DESY), Richard White

RW presents one of the old SST documents that contains all the Prod4 versions of the MC parameters; many plots from this document must be updated and compared with the CTA requirements, whereas the rest of the document can be copied into the WT8 Performance Analysis Report for the CDR.

• SL asks if the low-level performance studies should be done with dedicated software instruments or with CTAPipe; RW answers that many features are being cloned to CTAPipe right now, and thus it is good to use CTAPipe for this kind of studies too.

5 SST-Cam engineering tests transfert

Speakers: Dr Jason Watson (DESY-Zeuthen), Richard White

6 System engineering tests

Speakers: Cesare Molfese (Istituto Nazionale di Astrofisica (INAF)), Gino Tosti (Istituto Nazionale di Astrofisica (INAF))

CM reports that there are no updates about the STR, since it should not have stand-alone critical aspects to be verified with simulative studies.
