Just answer a couple of questions which were raised in the user's committee meeting.... > A filter wheel exists; they are now working on making it > controllable remotely. The filter wheel is currently controllable remotely. > It is not clear whether the chip in SPICAM is thinned. If it is > not, then (unlike DSC) SPICAM has very little response in the UV. The SPIcam CCD is thinned and AR coated with SITe's standard AR coating. This is not the UV optimized AR coating that is used on the Sloan u' chips or on the DSC chip. Plans for a head to head comparison of the u' throughput of each instrument during some engineering time are underway. -Alan APO APO APO APO APO Apache Point Observatory 3.5m APO APO APO APO APO This is message 127 in the apo35-general archive.
