HAM1 Both Doors are Removed

(Travis, Randy, Fil, Betsy, Marc, Jim, Gerardo)

Both doors for HAM1 are off, +Y and -Y. 
    - Y Door we had one of the O-rings get stuck to the door, used the tool to set the O-ring back into its groove without a problem.  No further issues.
    + Y door, we took a peek at the O-rings and they looked suspiciously good all over, even with a small gap, but then out of the sudden one of the O-rings jumped out and dropped to the floor.  So, the +Y door has the flange protectors over a single O-ring.

Purge air was turned up.  A photo of the dew point is attached, this as measured this morning by Travis.

A big "thank you" for those that helped with the cleanroom moves.
