  * Pedestal 1 par 1 (all 31) : 737970

Le canal 15 ne fonctionne pas


  * Run de verification (737972)
    * On observe un comportement bizarre sur la piste 4 , on essaie d'aligner a 450

  * Run de verification (737973)
    * Meme probleme

On prend commme piedestal **737970**

  * Tous les canaux allumes + cable d'injection (737974)
    * mean ~ 474
    * RMS ~ 2.5 cx bruyants 3.3

Threshold= 474+5*3.3 ~ 491

On essaie on doit mettre **496**

Si on regarde la calibration cela nous donne

**VTH (mV)= (496-474)/0.1743 = 126 mV**

mais la calibration n'est pas sur un canal mais sur les 2 cotes

donc **seuil minimal ~ 63 mV ou fC**

Pas si eloigne que ca des 50 fC prevus
