Metadata: STEO field

STEO stands for stereo. "Y" means Yes there is an adjacent photograph of the same area. "N" means No there is not.

Generally, both members of a pair must have the same exposure (EXPO) value. Usually the STEO field is "Y" only in cases where both have normal exposure. Some variable exposures might work for stereo viewing.

To find stereo views, look for values of "Y" in the STEO field in adjacent frames of the same mission and roll.

This field is not being cataloged beginning with STS093 (July 1999).
