*We will take a set of 1H(e,e’p) measurements to check the angle and dp/p offsets for the spectrometers. Use a current of 50 μA if possible. Rotate both HMS and SHMS to -27.5° again (or keep them there if already at that angle). Keep both HMS and SHMS at a central momentum of -3.609 GeV/c. First use the sieve slit on the SHMS side and the central Carbon optics target. Use the Particle Id. trigger, and measure about 2K singles in SHMS (that should take about one hour). Now install the 10 cm hydrogen target and measure about 2K singles in SHMS (that is again about one hour). Now take a coincidence spectrum in the same situation, again a measurement of about one hour. Remove the sieve slit on the SHMS side and use the large collimator. Measure a coincidence spectrum for one hour (rate should be 4 Hz, so this will get >10K statistics). Now install the sieve slit on the HMS side and measure another coincidence spectrum for a few hours (a few K statistics).

*Take runs to acquire roughly 10K events for HMS (use the large pion collimator!) at angles of 27.5°, 28.8°, 30.1°, 24.9°, and 26.2°. For SHMS at identical angles but also at angles of 31.8°, 33.5°, 35.2° and 23.2°. Roughly, at the central setting you need 45 minutes to acquire 10K statistics, and less at the lower angles, but perhaps 1.5 hour at 30.1°, and up to 5 hours at the largest SHMS angle of 35.2°.
