This text file lists "flat maps", which are maps that do not have topography (have no attached MAPFILE or images).
FLATLIST.TXT is output by residuals based on the following landmark HFLAG status:
HFLAG = T - The landmark has topography--it has an associated MAPFILE and images
HFLAG = F - The landmark is a flat map--it has neither an associated MAPFILE nor attached images
residuals inspects the .LMK files for each landmark stored in LMRKLIST.TXT and collects the landmark name and scale (km) for every landmark whose HFLAG is NOT set to 'T'. It stores these landmark details in FLATLIST.TXT.
Here is a sample FLATLIST.TXT file:
LANDMARK name resolution [km] EE0001 0.00010 EE0002 0.00010 EE0003 0.00010 END
