Flat Field of Lens
While copying disks, I have been looking at some of the images. The I (I
have not studied the V) looks quite flat to me. This compared to what I
saw on a camera lens where the edges were down by 50%. I think ROTSE has
seen similar loss off center with their camera lenses.
I cannot "see" any non-flatness. There must be some. I could not detect
any on the flat cutting it with sections. I could surely see 2%. I have
to conclude that Elliot did a good job.
This is a little project for someone to do on the disk 17 data when you get
it. Just use the sky to measure the lens flatness.
