Shell script for creating GMT plots of station or baseline time series 
 from the values extracted from a GLRED prt file or GLOBK bak file by 
 sh_globk_scatter and multibase. 
 
 Basic usage : 
 
    sh_baseline -f mb*  
 
        -f     :  Files from multibase to be plotted; all begin with mb_ 
 
    or  -F <filename>  where <filename> is a file containing a list of specific mb_ 
                       files (baselines/stations)
  
 Type 'sh_baseline -help' to get a full list of options 
 
 Type 'sh_globk_scatter' or see the GLOBK manual for examples of a full sequence 
 of runs to go from GLOBK files to station or baseline repeatabilities.
