'''Purpose:''' List of maplets whose difference between predicted and observed pixel/line locations in attached images is greater than a user-specified limit, or who have two or fewer overlaps attached to them.

MAPCHK.TXT is output by [[residuals]]. 

Landmarks are listed in MAPCHK.TXT for one of two reasons:
 * The first parameter input to [[residuals]] is the user-specified pixel shift limit. Landmarks which show a difference between predicted and observed pixel/line locations in attached images greater than this limit, are listed in MAPCHK.TXT;
 * If the number of overlaps attached to a landmark is two or fewer, the landmark name is listed in MAPCHK.TXT with an 'o' beside it.
