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
