also suits empty frame runs.

Comments: First laser does not have a red peak at the center, but maybe okay for this shift.
Attaching PSB and GPS screenshots, as we need to monitor them regularly.
At 6:18 to 6:40, we started getting four rings from the PS Booster. The 1st ring had a fairly low intensity, and the operators later dropped it. These times were confirmed
exactly with communication with PS operators.
again.
