L4C seismometers number 23 and 25 have been removed due to their proximity to the during-vent storage location for the HAM6 doors. 

I have not removed #21, but if it is at all in the way, please feel free to do so.  It is a passive instrument, so all that is needed is unplugging the DB9 connection that is within ~12 inches of the sensor, and then lever the sensor off the epoxy.  The sensor and cooler can be stored next to any other out-of-the-way sensor, and I will re-install them once the vent is complete.
