    keyword=Additional data taking and NaI check before energy change

    Before energy change (~9 am), we plan to do the following:
    (we already completed the initially planned data taking)

    Because of large hydrogen background at low p settings for Pb+LH2
    target, we added LH2 running for all the low P settings (going up
    if time allows). We also would liek to take right arm at 922.593 MeV for He and Pb (which are the only settings do not have right arm data). Left will take some calibration data for NaI detector
    check-out, at 30 degree, 950 MeV with HV=1700 (as it is now
    for most of the data taking), and 1900, 1000.
