S1 and S2m time difference and corrected time plots for run 2512 after initial time offset calibration:

Beta 2512.gif

The left figure shows that the time differences are fairly well calibrated, but the corrected times show some shifts for a few paddles in S1 and S2m. The beta spectrum shows some discontinuities that I thought might be related to the time offsets shifts. I will present more on this in the discussion below. The resolution in beta is about 0.14.
