RGA data before & after valving in two corner NEG pumps

RGA text file attached with scans before-during-after valving in last two NEG pumps in corner station (NEGs within several feet of RGA). Gerardo will note the times that he valved in each pump in order to correspond to RGA scans. We were looking for changes in H2 partial pressure but didn't see much change by simply eye-balling the RGA scan; attached is PDF of scan after pumps valved in - H2 partial pressure was at ~ 1e-7 A before and after.
