Change to ISC_GEN_STATES.py

While trying to reach GREEN_WFS_OFFLOADED during initial alignment, I got a coding error in both ALS_XARM and ALS_YARM (see attachment). With Georgia's help I traced it to ISC_GEN_STATES.py, where a list was being passed as a parameter when it should have been an index of that list. I added the index, saved the changes, and reloaded the ALS_XARM and ALS_YARM nodes. The errors are gone, I haven't seen if it affects anything else yet, as we can't get Y-arm to GREEN_WFS_OFFLOADED anymore due to ~60 mph wind.

 

On line 161 in ISC_GEN_STATES, I changed:

lock_fm[index].ramp_gain(lock_gain[index], ramp_time=lock_tramp, wait=False)

to:

lock_fm[index].ramp_gain(lock_gain[index], ramp_time=lock_tramp[index], wait=False)
