PS

Саша - Xi2/ndf + timepix residual vs cut Xi2/ndf

minor problems not influencing straws:

• dT periodic structure + low amplitudes (x-talk or clustering)
• - don't remember
• - dR distribution - very strange
• - pixelX = column = general Y!!! pixelY = row = general X!!

Drawing with distances - Kirill?

Dima - merging efficiency timepix-caen? azalea-caen merging 100% for run182. Run182 - check T0 source (Sergey) UPD was our scint

ongoing tracking

• run 163 (h2GeV) - done (merging azalea-caen ongoing based on time only) - crucial!!
• - run 180 (e2GeV) - done, merging ok but strange correlation
• - run 182 (h2GeV) - done, merging ok but strange correlation - run 174 (h10GeV) -done Sonja waits for merging

 

Gatchina

Natalia - treats run 84, 85 (mu2e clustering)

Alexey - first iteration of CROSS reco (hits) + CROSS-caen merging for runs 84, 85. Merging efficiency at least 10% wrt trigger, wrt (trigger & both layer & straw signal with threshold) - 1-2% - in total 250kevts/h

Dima - merging mu2e-caen efficiency wrt trigger 80%
