Currently, the SRY part of initial alignment uses a leakage beam going to the REFL WFS.  However, with the reduced amount of light on those diodes after the HAM1 vent, there is no longer enough signal there to be useful when the PRM is misaligned.  So, we should (on Tuesday, or some other non-locking day) change SRY to use the AS WFS.  It seems like probably the reason it was using REFL WFS at all is that it was commissioned originally back at a time that there were no AS WFS installed yet, and we just never bothered to change it, since it was working.  But, now the time has arrived to switch it to use AS WFS.
