Took empty target data smoothly.
Trigger rate (TSL2A) is about 0.75 Hz/mA.
Ligit seems to be low: 1.1-1.3e-7
Runs taken: 7087-7091

Meanwhile, some more time was devoted to find the back
scattered photon position around calorimeter (details
are documented in the e-log). The early trials of moving
the hodoscope to find the position partially failed.
The current false asymmetry is substantial - we're
taking empty-target data, thus not critical. The reason
needs to be investigated; a) hodoscope frame may be blocking
the beam un-evenly, b) laser beam position is way too off.
