[clas12_rgk] Fwd: Start time correction studies for events with the electron detected in the FT (no electrons in CLAS)

[Annalisa D'Angelo]

Dear RGK collaborators,

please find in attachment the message sent yesterday to the software 
people interested in the implementation of the start-time correction for 
events with electrons in the FT.

We did not receive a reply yet, but in today's software meeting the item 
was included among the high priority ones in Nathan's to do list.

All the best

Lucilla and Annalisa

Dear Raffaella, Veronique and Nathan,

As already anticipated we are working on the implementation of a version 
of event the start time calculated from the FT information for events 
that do not have an electron in CLAS.

Please find in attachment the latest results for both simulated data 
(from the K Lambda electro-production channel) at 7.5 GeV and for a well 
calibrated run 4013 - skimmed for two forward opposite charged particles 
and one positive central charged particle and the electron in the FT.\

As you can see the impact on the particle ID is relevant, especially for 
the positive tracks, both for forward and central particles.

We believe it would be important to use this kind of corrections for 
events with no electrons in CLAS to attribute the correct particle ID in 
the EB, at the time of runs cooking.

Should you think that more tests are needed we are ready to perform them.

Do you think it would be a good idea to present this studies at the next 
software meeting?

All the best

Lucilla and Annalisa
