What are the ranges of poses in the still images?
A pose flag will be added to experiment description file. Specifications will follow. If the pose flag is set to frontal, then all still images will nominally be frontal. If the pose flag is set to non-frontal, then the limits of right/left rotation are approximately 45 degrees left and right, and the limits of up/down rotations are normal head range. Combination of left/right and up/down are possible.
