Dsvid requested more PICS focus procedures and tests so I will go down
to GONG to do the weekly PM before I start on PICS.

PICS  COMMENT: Mon Aug 30 18:42:26 GMT 1999
Stopping to set-up for further focus tests.  Installing Hartman mask.
Will attempt to determine which way to move the collimator in order to
refocus it at 2300 microns closer to the occulter, then, I will run 
focus steps with the camera in 100 micron increments to find the
best focus.  moving the collimator will theoretically focus the disk and
limb images at the same place.  The focus at different camera positions 
now.

PICS  COMMENT: Mon Aug 30 19:06:03 GMT 1999
Start position for camera is 15371.  Swapped cables, collimator position
indicated as 15370.  Moved collimator to 17672 (+2302).  Swapped cables,
Camera position now read-out as 17672, although it is secured and did 
not move.  Loosened camera hold-down screws and will begin focus
test to see if moving camera to higher micrometer values improve the 
focus.  I will do this in approximately 100 micron increments, the 
micrometer values will be written to disk along with the images.
Using focus routine in cmdtool developed on Friday.
Mon Aug 30 19:12:22 GMT 1999	PICS	 Start Focus
PICS  COMMENT: Mon Aug 30 19:28:15 GMT 1999
Ran camera from 17672 to 18276 in approximately 100 micron increments.
Could not really see improvement in focus, although focus did not get
worse until the last couple of steps.  I will return camera to original
position, 17672, and the start test over after moving collimator in
other direction.
PICS  COMMENT: Mon Aug 30 19:33:42 GMT 1999
Moved camera micrometer back to 17683, pushed camera "up" against micrometer
shaft.  Swapped cables, collimator position read at 17682 on micrometer
controller.  Moving it back to original position (-2300 microns) then 
in opposite direction (-2300 microns) to approximately 13082.
PICS  COMMENT: Mon Aug 30 19:41:37 GMT 1999
Collimator position at 13070 on micrometer controller.  Swapping cables.
Repeating focus test, increasing Camera position in 100 micron 
increments.
PICS  COMMENT: Mon Aug 30 19:43:22 GMT 1999
Camer focus test start position now changed to 13070 on micrometer 
controller.

PICS  COMMENT: Mon Aug 30 20:03:47 GMT 1999
It was very difficult to tell which direction was better.  My gut feeling
was the second set of tests -- decreasing the collimator micrometer values
-- made the focus worse, but the changes were subtle at this end and with
no animation or flicker tool, comparison was difficult.  I will email
David to take a look at the images and agree or disagree with my assessment
and also to determine if further focus tests are needed beyond the tests
I did at each collimator position is needed.
Setting collimator and camera back to original positions.

CHIP looking at dome,  stopping to reconfigure dome shutter.

PICS  COMMENT: Mon Aug 30 20:35:37 GMT 1999
Set things back and then moved camera to David's "good disk focus" 
position.  Ran one more Focus loop but micrometer value did not get
entered correctly.  Only "671" may have gotten into header.
Repeating with the correct micrometer entry of 15671.
PICS  COMMENT: Mon Aug 30 20:40:47 GMT 1999
OK, test done for now.  I will not secure covers for now but I will
remove Hartman mask and resume Patrol after getting out of Focus.

PICS  COMMENT: Mon Aug 30 20:58:49 GMT 1999
Stopping PICS after the 2100 UT series and will set up for
follow-up tests.  After some analysis, David determined that we should
move the collimator -6900 microns from the original position and
move the camera +600 microns from the original position.  I will run 
thru a range of camera positions around that value before securing
the camera for the day.

PICS  COMMENT: Mon Aug 30 21:15:57 GMT 1999
Installed Hartman mask.  Moved collimator from 15671 to 8767 microns,
approximately -6900 microns.  Unsecured camera.  Camera start position
= 8767.
PICS  COMMENT: Mon Aug 30 21:21:32 GMT 1999
David thought the range for the test would be +/- 1000 microns around
new theoretical good position of +600 from original so I moved the 
camera -400, 1000 microns away from new "good" position and will run
thru a range to +1000 to the other side (toward rear).

PICS  COMMENT: Mon Aug 30 21:37:21 GMT 1999
Steps in approximately 100 microns increments will be uneven because
I cannot back up without going upstairs and pushing on the camera
due to the weak spring.
PICS  COMMENT: Mon Aug 30 22:00:51 GMT 1999
Images got bad after passing the +600 setting (9367) in the positive 
direction (further back), but went thru the test anyway.  Double
images on disk very obvious at +900 (10230) from best guesstimate
of +600.
PICS  COMMENT: Mon Aug 30 22:05:09 GMT 1999
Test pau.  Setting camera forward to 9325.4 which is David's best
guesstimate.  Collimator left at new setting.

Running a Focus ta last secured position.  Collimator is 8767 (-6900
from original position).  Camera is at 9325 (+600 from original position.)

PICS  COMMENT: Mon Aug 30 22:21:02 GMT 1999
Shutting down for the day, I will leave the PICS as is, with covers off
for a quick start on any changes David and Tony might specify after
looking at the test results.  We will resume tomorrow morning.
