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:

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:

EE0001        0.00010
EE0002        0.00010
EE0003        0.00010
