Dear Raffaella, Veronique and Nathan,<br>
<br>
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.<br>
<br>
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.\<br>
<br>
As you can see the impact on the particle ID is relevant, especially for the positive tracks, both for forward and central particles.<br>
<br>
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.<br>
<br>
Should you think that more tests are needed we are ready to perform them.<br>
<br>
Do you think it would be a good idea to present this studies at the next software meeting?<br>
<br>
All the best<br>
<br>
Lucilla and Annalisa<br>
