    Optics runs with open collimator after cycling electron quadrupoles to 1600A.

    Hadron arm momentum was decreased from 1GeV to 0.6GeV (the history before
    that is unknown; probably they went to 1GeV from negative polarity).

    Electron arm runs:

    1198 -4% 10cm dummy
    1199 -4% 15cm dummy
    1200 -4% 4cm dummy
    1201 -4% 12C
    1202 -3% 12C
    1203 -2% 12C
    1204 -2% 4cm
    1205 -2% 15cm
    1206 -2% 10cm

    hadron arm went from 1Gev to 0.6GeV before these runs

    1210 0% 10cm with hadron arm at 0.6 GeV
    1211 0% 15cm with hadron
    1212 0% 4cm with hadron; beam tripped just before end of run
    1213 0% 12C with hadron
    1214 test run

    Electron arm runs:

    1216 2% 12C electron arm only
    1217 2% 4cm
    1218 2% 15cm
    1219 2% 10cm

    1220 4% 10cm
    1221 4% 15cm
