NAME

6       x_setup - Determine Pairs of Legs that need Cross-Over Checking
7

SYNOPSIS

9       x_setup [ -Llegfile ] [ -Rwest/east/south/north ]
10

DESCRIPTION

12       x_setup  scans  the  gmtindex.b file that contains information on which
13       legs occupy each 1 by 1 degree bin and reports all the  pairs  of  legs
14       that may overlap. Each pair is only reported once, even if the two legs
15       involved are found in other bins also.
16
17       -L     Only report pairs where at least one of the legs are present  in
18              the legfile.
19
20       -R     The region of interest.  [Default is world]
21

BEWARE

23       The  -L  option  is useful when one wants to check out a handful of new
24       cruises. Obviously we only need to compute  COEs  for  the  pairs  that
25       involve one or two of the new cruises, since all the other combinations
26       have already been done.
