Hello all,
As per the definition of Emission angle given in http://ode.rsl.wustl.edu/moon/pagehelp/quickstartguide/index.html?seach_page.htm#filterbyanglerange, higher values of emission_angle indicate more oblique viewing. Consider the two LROC products M1099037220LC and M1108467737LC with a very close emission angles of 1.78 deg and 1.76 deg respectively. However M1099037220LC appears to be very oblique with elliptical shaped craters and M1108467737LC appears to be nadir looking with almost circular craters. Can you please explain why is it so ? The screenshot of the LROC images are attached for you reference.
Thank You,
Shyam.
