all Observer B readings are low.
Rotating rhamboids-made na difference in resol.utian readings at 11.X. No
further. rotating o:E rhomboids was therefore performed.
Rotation of Rechan prism made no significant difference in resolution
readings at 11X. Rotation of -the Pechan was performed on7_y occasionally
thereafter.
?Resolution readings were discontinued because of time and because light
intensity was, determined to be below specs,
