ER14 Sweep #1 performed

This morning, Daniel, Richard, Jenne, and I performed a sweep of the LVEA in prep for logging some ER14 Observation Mode overnight this week.  We did not prep everything for O3 since this and next week are still heavy in PEM injection and Calibration work which need equipment plugged into lots of places.  We also DID NOT do the end stations since we have quite a few Tuesday Maint items at the end stations tomorrow and will perform the list then.  The checklist item status after the morning sweep is as follows:
