2. The methodology for calculating the minimum height above ground level at which each optical camera installed on the observation aircraft may be operated during an observation flight, including the value of the contrast ratio or the equivalent modulation to be used in this calculation, which shall be not less than 1.6:1 (correspondingly 0.23) and not greater than 4:1 (correspondingly 0.6), shall be determined within the Open Skies Consultative Commission during the period of provisional application and prior to 30 June 1992. The ground resolution of optical cameras shall be determined from a visual analysis of the image of the calibration target on the original film negative. The numerical value of ground resolution shall be equal to the width of the smallest bar of the calibration target that is distinguishable as a separate bar.
