 Purpose:  To sample the CCAS and telescope IQ at the same time under a series of conditions (wind, seeing, temperature etc..).  For the moment, Hanshin thinks that 1.5 arcsec FWHM at the guider field would divide the good seeing from the bad seeing.   Somewhat specific condition he is interested in is a high-wind condition. The last test indicataed a correlation between high-wind and image quality (more specifically only small increase in the contribution from an effect suspected from the area between CCAS and M1 while significant increase in the contribution from an effect suspected from somewhere above the telescope). But this was only one short track (15min). 
 
-Frequency:  Please take this test as often as different conditions present themselves during this bright run.  (We have typically been aiming for 2 times per lunation.) This procedure and the preceding stack are being logged as engineering time.

 After 3 minutes* repeat steps 14-21 except the HEFI sequence number does not get set to 1.  Continuing repeating until you have done this test 5-7 times to fill the central ~50% of the track.

 *Hanshin says that it is not necessarily required to pause for these 3 minutes.
