[GRASS-user] Correction of terrain effects for MODIS data?

I got the 2nd edition of the GRASS-GIS book from a friend.

Excellent! It is one of the best introductions in GIS and RS that I have
seen. Special attention is given to the terminology used in the field of GIS
and RS which is very important... as we tend to use language(s), very often,
not correct.

I tried to follow the example for correction of terrain effects in a MODIS
surface reflectance NIR band 
(...as far as I know, MODIS surface reflectance imagery is only corrected
for atmospheric effects).

I don't get the desired results... The output is too bright from what one
would expect it to be.

Any recommendations?
