HMS	-1.576	30	3/4 e^- PID	sieve	PS1=
SOS	-1.290	30	3/4 e^- PID	sieve	PS2=

HMS current&field settings:
cdaqs1> ~cdaq/FIELD/field99
Input HMS momentum in GeV, electron is negative.
-1.576
Set current for Q1 =     204.62842198462 amps
Set current for Q2 =    -162.61167176023 amps
Set current for Q3 =     79.874587716980 amps
Set NMR for Dipole =   -0.43187710604559 Tesla

Beam 10 uA, position IPM3H00C X=0.0 mm, Y=-1.5 mm

Fast Raster ON: dx=+- 0.5 mm, dy=+- 0.5 mm

With central carbon take large statistics run for HMS and SOS (at least 100 counts per hole, ca. 25K each spectrometer). Verify that BPM and FR are in DAQ.

Take similar large statistics runs with quintar, at least 100K in each spectrometer.
