Optics Performance

Wednesday we worked to explore the image performance as a function of detector position relative to the field correctors.  We got pretty good images over the whole field of view, but the seeing was poor.  We’re thinking we’ve got to vent this dome – the skin gets really hot during the day and the closed telescope tube takes a long time to cool off.

Thursday we cleaned, cleaned, cleaned!  We put things on UPS’s, rebooted everything to ensure that we can run remotely (or robotically), and finally drove down (during the day!), very tired but very pleased.  ATLAS is now real.
