1. Stereo Point Transfer Device - Accuracy. Question the pointing
accuracy (repeatability) in the comparator mode. Pointing error wa
approximately the same as the accuracy ?L,5 + .005% of the distance.

curacy and test procedures.
Vacuum Hold-Down. New 0 glass with microgrooves having
edges shown definite promise for practically invisible grooves.

3. Controls. ngineers reported that the joystick types re-
quested by us would ecet in small quantities. In addition, there
may be practical and economic limitation to the degree of control requested
on the joystick. Dagreed with the right hand joystick, left hand
auxiliary control concept. They were advised of users' reservations at
having extensive control in joystick. They will continue to analyze prob-
lem and prepare a recommended layout in the near future.
4. Zy* Station Module. 0 proposed a boom type support like that
on an overhead supported radial saw. Assembly would not rotate. Oculars
would. Vertical displacement would probably be motor controlled. Monitor
agreed that this appeared to be satisfactory.
5. High Intensity Illumination.
a. Contractor again warned of color temperature specification
(3400?K min). Dimming must not be accomplished through lowering color
temperature to objectionable level. reported that the
chosen lamp had a normal operating color temperature of 3700?K and
that it could be dimmed to 10without going 3000?K. The monitor
agreed that such performance would be acceptable.
b.. The problem of adequate brightness at all magnifications was
discussed again. was discouraged with the low magnifica-
tion problem. He quested elimination of the law magnification ob-
jective. Further discussion revealed that the glass
may alleviate fhe problem. I I will nv . contract
monitor ataed that 4+00 foot lamberts-Ts not adequate, but that all
magnifications should have at. leant 1000 foot lamberts.
