Polarization Measurement

1.

Make a note in the logbook of the target angle on the scale, seen with the TV camera.

2.

Take 6 runs of data with the given angle, each run of about 20-30k events (30k at $E_{beam}<2$ GeV).

3.

Ask the MCC to turn the target to 38 units and make a note of the angle on the scale.

4.

Take 2 runs of data with the given angle, each run of about 15k events.

5.

Ask the MCC to turn the target to 76 units and make a note of the angle on the scale.

6.

Take 6 runs of data with the given angle, each run of about 20-30k events (30k at $E_{beam}<2$ GeV).

7.

Analyze the data

1.

$adaqs3\%PAW>$ exec run run=???? and

2.

$adaqs3\%PAW>$ exec asymp run=???? angl=tang, for each RUN, $tang$ is the target angle observed on the scale.

3.

$adaqs3\%PAW>$ call prunpri.f(9916,9950), print a table with the results for a given range of runs.

4.

$adaqs3\%PAW>$ shell  cp  runs.tab  #<3419#>moller/public_html/tab/run.tab.9916-9950, copy the table to a database.

5.

$adaqs3\%PAW>$ exec pol_sum run1=9916 run2=9950, average the results for this measurement.
