SECCHI Shutter Mechanism Spin Times |
Polarizer Spin Timesas of 2017/12/21 (COR 1-B 2014/09/30) Note: For Feb.-Oct. 2012, the COR 1-B polarizer data points are a change from previous. A CCW test is done before the CW test. For previous CCW tests back in 2007, the mechanisms were first spun CW, then CCW. For 2012 the order was reversed. This change was implemented for all polarizers starting 2012/04/17, and then discontinued in October 2012. |
