keyword=Helicity mode test

We have performed a series of helicity mode test. From online analysis, HRS DAQ agrees pretty well with HAPPEX DAQ. When large charge asymmetry has been generated, both of us are measuring 2.2% (HRS DAQ) and 2.4% (HAPPEX DAQ). The following table gives various conditions with corresponding run numbers.

Most of the settings are also recorded correctly in the end of run halog entry except Random/Toggle mode. In the end of run entry, it always says "OFF".
