Dear Latifa,
sorry for not attending the meeting the other day. Here is where we stand
for CND:

3134-3214: timing completely off but I guess these runs are not going to
be used (bad RF as well for most of them)? If they are needed, I'll need
to calibrate one run in this range.

3215-3222: if these runs are used, I'll need one run from this range.

3306-3547: I need one run in this range (I think I asked it at the
previous iteration too but the file was not cooked)

The rest looks pretty acceptable, aside from these "individual" (or groups
of 2, 3 runs) runs showing jumps in the timing calibration (but are these
good and required production runs?): 3549, 3782, 3863, 4142. If these are
necessary runs, I'll calibrate them all as well.

Best regards,
Silvia
