DPMON COMMENT: Fri Oct  7 23:15:40 GMT 1994
Restarting patrol with optimum limb setup.
I found the reason for the change in Daystar vignetting throughout the day.
As we correct for occulting by moving the O1, the bright spot moves across
the disk image, probably due to the slight tilt of the O1 as the telescope
moves about the gimbal.  I tried using the occulting corrections while taking
disk images manually and found the same trend that we see during the day.
Therefore we have to set the Daystar tilt so that the disk images aren't
vignetted for a particular time of day, probably the morning when we get the
best data.
