Run 3 converter: addition of OTF V0s #23731
Conversation
- Added the Gamma Conversion V0s from the PWGGA - Added a histogram to the PCM analysis to save the pT spectra of V0s before ANY cut - When running over AODs the labels of the GammaConversion daughters need to be sorted. This can be done in the V0Reader task and with my latest changes also in the ConverterTask. To ensure that this is only done once there is a security check. This check was also updated inside the V0Reader. - On the fly V0 table now uses truncation: - 11 bits for length and mass variables - 13 bits for momentum variables - In case of AOD -> AO2D we can now use the AliConverionPhotonCuts class to cut on the on the fly V0s. This helps to reduce data size and ensures that we can use the same cuts for converting from AOD and ESD. - Added possibility to convert on the fly V0s from ESD to AO2D. This requires the V0Reader class to be added to the analysis chain. Also we now need to specify what collision system is used `fCollSystem` via `SetCollSystem` and what the conversion cuts `fConversionCut` are via `SetConversionCut`

@mhemmer-cern when you get around to it, can you also write to this PR a message explaining the latest status of the data volume after all the reduction steps you took, since it's now much better? Thank you!! |
|
@mhemmer-cern sorry to insist, but this is just a ping for you to report here on the size reduction you did - after which imho this could also be merged for testing. Tagging also @maciacco . Thank you!! |

The reduction we saw was from 20% to 6% in PbPb data, just by truncation and cutting. |
This commit (from @mhemmer-cern - super thanks!) adds a path for saving on-the-fly V0s in our converted AO2D. I'm marking this as draft for discussion and will still make a few minor changes (mccollisions version bump to 001, for instance) before marking ready for review.
