Issues on resolution, 3 different sentences states 3 different resolutions: 1-"At an altitude of 250 km from Mars, SRC can produce images with a resolution of 2.3 meters/pixel of 2.35 km square Mars terrain" 2-"A typical image from HRSC of Mars has a resolution ranging from 12.5 for nadir (directly down) to 25 m/pixel for the farthest off-nadir shots" 3-"By the start of 2015, about 70% of Mars had been imaged by Mars at resolutions greater than 20 m per pixel, and 97% at resolutions of least 60 m per pixel"

1 This is the description of the instrument, I think that the issue is that Mars Express orbit at more than 250 km above the surface (this is not clear enough).

2 Those values are true only at periapsis (ie when Mars express is the closest to the surface).
