If an echelle observation is interrupted for the GRB program the observer will have the advantage that there will not be an instrument switch at the MC, but there will also not be a tertiary rotation required so the echelle observer may not have much time to get his or her frame. When we commissioned the echelle I believe we determined that there was no noise penalty for reading out the CCD while slewing the telescope, and this group may want to take advantage of that fact. I would urge someone to verify this before trusting that nothing has changed in the meantime, but it seems worth mentioning that at some point this was the case. --Connie Rockosi APO APO APO APO APO Apache Point Observatory 3.5m APO APO APO APO APO This is message 16 in the apo35-echelle archive.
