Resolution estimates of the 18 chips, 3 scenes, are provided as requested. The
user is cautioned as to the subjetiveness of these estimates since resolution
targets are not imaged on the chips. Brainstorm imagery served as a guide for
assigning values to the chips. /Since a direct quality correlation existed between
all 18 chips, with 6 groups of 3 chips each, they were assigned resolution values
as follows:
Chip Numbers Subjective Resolution (inches)
18, 33, 17 1.7 - 2.0 v/
