x_setup - Determine Pairs of Legs that need Cross-Over Checking
x_setup [ -Llegfile ] [ -Rwest/east/south/north ]
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
-R The region of interrest. [Default is world]
The -L option is useful when one wants to check out a handful 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.
