APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday August 16, 2003 (MJD 52868) ---=== OBSERVING TEAM ===--- Steph Snedden ---=== OBSERVING PLAN ===--- Spectro monthly checkout (aka pre-shake shake) ---=== OBSERVING SUMMARY ===--- Spectro monthly checkout, as advertised. ---=== OBSERVING LOG ===--- Spectro monthly checkout completed. Since the spectrographs had just been reassembled, I expected some complications, but was pleasantly surprised. All went smoothly. Kudos to the engineering crew. After positioning the fiber images on the CCDs and adjusting focus, the new collimator actuator positions are: sp1: sp2: A -4204 -3038 B -4404 -3238 C -4704 -3338 Of course, the actuator readings were originally zero, since the spectrographs were powered down for disassembly. Dithered flats plus two arcs taken. No tape was shipped, so if these frames are to be archived somewhere, that should be done before the data is removed from 'host.
