NAME
X_SETUP - Determine Pairs of Legs that need Cross-Over
Checking
SYNOPSIS
x_setup [ -Llegfile ] [ -Rwest/east/south/north ]
DESCRIPTION
x_setup scans the gmtindex.b file that contains information
on which legs occupy each 1 by 1 degree bin and reports all
the pairs of legs that may overlap. Each pair is only
reported once, even if the two legs involved are found in
other bins also.
-L Only report pairs where at least one of the legs are
present in the legfile.
-R The region of interrest. [Default is world]
The -L option is useful when one wants to check out a hand-
ful of new cruises. Obviously we only need to compute COEs
for the pairs that involve one or two of the new cruises,
since all the other combinations have already been done.
