A question responding to Chris Garasi's query: It was my understanding that with a ~1" slit, GRIM spectroscopy is only very low resolution, something like 400 or so. Is this true, and if so, is this adequate for you to do the science you want to do? -Michael Strauss APO APO APO APO APO Apache Point Observatory 3.5m APO APO APO APO APO This is message 6 in the apo35-grim archive.
