    keyword=rate at ep kin-3.

    Rate estimate for kin-3 ep.

    At E0=0.684, theta_e=61.4, E'=0.497, p_p=0.62, theta_p=44.18.

    12.9 uA beam on 15 cm LH2 target, luminosity=5.1*10^37 cm^-2 s^-1.

    for 6 msr electron arm solid angle, electron elastic singles rate
    should roughly be about ~7 kHz.

    Run 5349 for example, at I=3 uA, electron singles rate should be about 1.6 kHz. We have T1= 1.2 kHz, T5=0.76 kHz, add up roughly right.

    Since we are not doing elastic cross section measurements in the next few days, as long as we record coincidence events, we will be fine in the data analysis.

    If we clearly see evidence of ctime off, we should tune it to be
    roughly right. Otherwise, we will just need to take T5 events and increase the beam current.
