NAME

       x_remove - Remove COEs for Selected Cruises from the Data Base

SYNOPSIS

       x_remove removefile [ -Xxbase ] [ -Llegbase ] [ -V ]

DESCRIPTION

       x_remove  will read a list of ’bad’ cruises, read the XSYSTEM data base
       files, and write out new XSYSTEM files that do  not  include  any  COEs
       generated  by  the  bad cruises. This is useful if certain cruises turn
       out to have systematic errors (e.g. the topography values were inadver-
       tently given as fathoms instead of meters), and we would like to re-run
       xover/xupdate after the systematic errors have been rectified. The  new
       file  names  will  consist  of  the old file names with the suffix _new
       appended.

       -X     Indicates alternate xbase file [Default is xx_base.b].

       -L     Indicates alternate legbase file [Default is xx_legs.b].

       -V     Means operate in verbose mode.
