A quick Nyquist question...

If one particular sensor/lens combo has an MTF at Nyquist of 0.28 and another has an MTF at Nyquist of 0.37, am I right in thinking the 0.37 combo has a higher resolution, or does that even mean anything?

I am asking this because in NASA's LRO camera specs sheet (http://lroc.sese.asu.edu/about/specs) says the two narrow angled cameras have a MTF at Nyquist of 0.28 and it's wide angled camera has 0.37. It mentions the sensor in the wide angle camera is a Kodak KLI-5001G, designed for scanning applications, with just with 1 x 5000 dots resolution, the other dimension, which is variable, is created as the camera scans over the Lunar surface from Orbit.
