Hi Taylan,
when we ran staright tracks last time, we suffered greatly from not having
a suitable trigger and/or proper high prescaling factors of all other
triggers besides PHYS0. I'm not sure if this is available now.
For simplicity I would recommend the same trigger setting but to use Coda
readout lists with high prescale factors for PHYS1-6. Let me know if you
need help.
Regards,
Michael
