 data are purely oscillatory. This option may not be appropriate for all

 data sets.								



 If the x2file=  option is set, then the values from the specified file

 will define the set of "acceptable" values of x2 for xpicker to	

 output. The format is a single column of ASCII values. The number of  

 specified values is arbitrary.					



 Such a file can be built from an SU data set via:			

     sugethw < sudata key=offset output=geom > x2example 		



 If the value of x2file= is not set, then				

 xpicker will use the values specified via: x2=.,.,.,. or those that are", 

 computed from the values of f2=  and d2= as being the "acceptible

 values.								



 See the selfdoc of  suxpicker  for information on using key fields from

 the SU trace headers directly.

 Endian stuff by Morten Pedersen and John Stockwell of CWP.

 Interp stuff by Tony Kocurko of Memorial University of Newfoundland

 Modified to include acceptable values by Bill Lutter of the

     Department of Geology, University of Wisconsin 10/96

 MODIFIED:  P. Michaels, Boise State Univeristy  29 December 2000

            Added solid/grey color scheme for peaks/troughs

 

 G.Klein, IFG Kiel University, 2003-09-29, added cursor scrolling and

            interactive change of zoom and clipping.



 NOTES:

 Interactive picker improved to allow x-axis of picks to be

 coordinated with "key=header" parameter set in driver routine

 suxpicker. Multiple picks per trace are now allowed.



  Input:

  The command line of suxpicker is unchanged.  The parameter"key=header"

  set in  suxpicker controls a) trace x-axis  displayed via xpicker and

  b) the header values in the first column of a pick file either read in

     or written out from xpicker c) header values expected in optional file

      or written out from xpicker c) header values expected in optional file

     x2file= which reads into xpicker allowable trace x-axis values.



   a) example command line:  suxpicker key=offset < shot10.plotpik



   b) pick file format:

	x-axis_value_1 time_1

	x-axis_value_2 time_2  

	x-axis_value_3 time_3

	etc.

	x-axis_value_n time_n



	pick file example:

         1000.000000 0.500000

         2000.000000 1.000000

         3000.000000 1.500000

         4000.000000 2.000000

         5000.000000 2.500000
