APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday April 26, 2005 (MJD 53487) ---=== OBSERVING TEAM ===--- Dan Long ---=== OBSERVING PLAN ===--- Spectro Monthly Checkout ---=== OBSERVING SUMMARY ===--- Spectro monthly checkout completed. Positions tweaked slightly. Focus also just slightly changed. It was set for 6 C using the actual spectrograph body temperatures. Hopefully this allows us to better track focus with temperature. Biases, Darks, and Dithered Flats also done. One glitch. During collimation a mechPiston -400 command to sp1 sent motor a -400, motor b -400, and motor c nearly +4000. It was the only failed/incorrect move of many (including the dithered flats). Fiducial tables built and installed. There were significant differences in the azimuth fiducial positions near the ends of the range ~600 ticks. The error was relatively linear away from the canonical fiducial, indicating scale error. ---=== OBSERVING LOG ===--- 23:50Z Doors Open, Fans On 00:50Z Doors Closed Biases: Now re-computing percentiles... % Compiled module: QUICKBIAS.

Using the spectrograph temperatures and the offsets, I am adjusting them to be in best focus at the current ambient air temperature tonight at 04:00Z of 6.0C. This would mean a -400 piston for r1 and a +1900 piston for r2. Moves of 1000 or less are generally not worth it, but being a little picky on the first spectro monthly checkout where temperatures are available seems worth trying at least once. It's likely we will find other parameters like flops and thermal equilibrium issues dominate at the 500 step level. sp1> mechPiston -400 sp2> mechPiston 1900 sp1> mechSend s spMechVersion v2_7_0 Bootup 798570289 SpectroID 1 SlitID 34 Air On Shutter_open_sensor Off Shutter_closed_sensor On Left_open_sensor Off Left_closed_sensor On Right_open_sensor Off Right_closed_sensor On Coll_motor_A -3155 Coll_motor_B -3554 Coll_motor_C -391 Requested_exp.time 0 Exp_time_left 0 Last_exp.time 0 Last_open_transit.time 725 Last_close_transit.time 550 Humidity 0 Temp_Median 8 Temp_Hartmann_Bot 7 Temp_Hartmann_Top 8 Temp_Red_Cam_Bot 8 Temp_Red_Cam_Top 9 Temp_Blue_Cam_Bot 8 Temp_Blue_Cam_Top 8 AD 3584 1294 sp2> mechSend s spMechVersion v2_7_0 Bootup 798570419 SpectroID 2 SlitID 2 Air On Shutter_open_sensor Off Shutter_closed_sensor On Left_open_sensor Off Left_closed_sensor On Right_open_sensor Off Right_closed_sensor On Coll_motor_A -2458 Coll_motor_B -3663 Coll_motor_C -3661 Requested_exp.time 0 Exp_time_left 0 Last_exp.time 0 Last_open_transit.time 725 Last_close_transit.time 630 Humidity 0 Temp_Median 7 Temp_Hartmann_Bot 6 Temp_Hartmann_Top 7 Temp_Red_Cam_Bot 7 Temp_Red_Cam_Top 6 Temp_Blue_Cam_Bot 6 Temp_Blue_Cam_Top 6 AD 1792 1094 For some reason mechPiston sent sp1 actuator C +4000 instead of -400.
