Table 1: Example of objects of known size measured with MBARS. Most images provide results that are within 1-pixel uncertainty of the known diameter. The measured heights (Hm) and actual heights (Ha, Fig. 1) are shown, with Ha~20 cm taller than Hm in most cases. Images marked I (for Inapplicable) were either not measured in previous works, or not available at the time of publication. MBARS should generally underestimate the lander width, as the full width could only be measured if the landers were perfectly perpendicular to the sun incidence direction.
