We are baking out some PMC PZTs in the countertop air bake oven in the OSB lab.  The oven is sitting on the counter against the long hall-way wall from the controlroom to the bootscrubber into the LVEA.  The oven has a fan in it that runs although we have never deemed this as a noisy source for interferometry.  I turned it on yesterday morning around 11am PT.  I will turn the second countertop oven on that is next to it today and both ovens will run over the weekend.  Please holler at me you anyone sees this as a problem, or if particle counts look funny in the OSB optics lab over the next few days.
