I have modified the MeasureSpotPositions.py script to accept the arms as valid cavities (it used to give an error "Sorry, this only works for MC right now").
There is still no wrapper script to turn on lockins and turn them off after the measurement, so I have not tested the arm A2L yet. But I should be able to tomorrow, or whenever the IFO is next available.
* Write the wrapper script (analog of mcassMCdecenter).
* Fix arm assOff, assDown, assOn, assUp scripts to match the current channel names (which were changed long ago to be human-readable, versus mysterious numbers).
