Looks like z vertex is not used in the update - is mean vertex used?

Updating the TPC using "real" vertex instead of the mean vertex would be preferable. However, I'm uncertain about the ease of implementation and whether a collision vertex is available at...

Hi @matthias-kleiner, The changes introduced in the commit above will most probably address the local X-match issue described in https://github.com/AliceO2Group/AliceO2/pull/12928#issuecomment-2023421138. As discussed previously (here: https://github.com/AliceO2Group/AliceO2/pull/12928#issuecomment-2023470047), it appears the "mean" vertex...

### Covariance matrix for qpt- source code to be checked * is the "overoptimistic" covariance matrix only in our skimming code or is the systematic error not use?

We've identified a persistent issue with the incorrect track covariance for TPCITS tracks in the skimmed data. To simplify debugging and further studies, I propose storing the following full tracks...

Hello @shahor02 , @matthias-kleiner , @wiechula and all. The data volume for track parameters is substantial, with 88 bytes allocated for 4 parameters. To enhance storage efficiency, I've suggested a...

Hello @shahor02 . Thank you for the clarification. Based on your input, I propose we first proceed with the options as I previously outlined. If I successfully implement relative track...

Hello @matthias-kleiner Preparing the combined tracking resolution and bias parameterization I had seen that the wrong vertex is used to fill the content. I am currently reviewing the source code...
