Pupil Montage from Allan Meyer

Allan Meyer took our pupil images from lineups when we held the door fixed and adjusted the angle to see when we vignette.  This was from the second night of line ops.  The image and copy/paste of Allan's email are below.




Made a simple 3x3 montage of the 9 images, after subtracting the initial 'centered' image, and rotating each ~85 degrees counterclockwise.

The numbers added on are the difference between the TA elevation angle and the door elevation angle (fixed at 30 degrees).

However I should check the TA LOS position while we were doing this.  It was probably near center, but if not could have introduced a bias of a degree or two.

Assuming small LOS, looks like the limits are +4 degrees and -5 degrees with respect to the door.
So at lower door limit of 24 degrees TA can go to 19 degrees, and at upper door limit of 57 degrees TA can go to 61 degrees.
