This file is a debugging file that is not used in normal operations. OVERLAPS.TXT is generated by the OVERLAPS subroutine and is specific to a particular landmark. It is read by LITHOS.f and DISCONNECT_LMFILE.f.

Additional Reference


This subroutine creates a file OVERLAPS.TXT that LITHOS uses to search
for maplets that overlap a given one (LMKNM).  It searches a list of
maplets in an input list (INFILE).  If a maplet has a resolution times
lower than LMKNM it is excluded.  If the maplet center differs in position
by more than twice the sum of its half width and that of LMKNM, it is
excluded as well.  The remaining maplets are those over which the overlap
searches will be made.

The input file is generally LMRKLIST.TXT, but this can be very large.
In some circumstances, such as when we are dealing with maplets that are
completely inside a BIGMAP, a file USED_MAPS.TXT generated by the BIGMAP
program that has all maplets used to construct the BIGMAP can be copied
into LMRKLISTO.TXT.  This will be read as the input file for this
subroutine, and it is guaranteed that only maplets in that file should be

Another important input file which should be read instead of LMRKLIST.TXT is LMRKLISTX.TXT. In the limit of a very large number of landmarks > 20 K, reading the LMRKLISTX.TXT file when you load a landmark into lithos will result in substantial time savings compared to reading the LMRKLIST.TXT file .
