[Offsets in MC]
I have introduce an offset in MC2 PIT because the PZT1 again started railing.
Right now the PZT1 EPICS value is within the range happily.
Please keep this MC eigen axis as a nominal configuration.
I have modified the IFO configure scripts such that XARM and YARM are locked with POX11 and POY11 respectively.
A big advantage in use of POX and POY is that we don't need to misalign ITMs when we align each arm.
Those scripts are now available from the C1IFO_CONFIGURE screen as usual.
