They <br>must be there, moreover there must be a lot of random noise: FTOF is <br>counting few x100 kHz. Are you sure you plotting all hits? Is there any <br>threshold or requirement of two side L-R reconstruction?<br><br>I would expect for every DC track to see the corresponding FTOF hit <br>(plus random noise), if it is not there we will not be able to reconstruct <br>anything.<br><br>Thank you,<br> Mikhail.<br><br><br>On Sat, 10 Nov 2018, David Heddle wrote:<br><br>> I just went to the counting house and the FTOF hit rate on ced looked<br>> normal.
