zp - namelist parameter file

zp2 can use a Fortran namelist parameter file to specify plotting parameters. The default name for this file is "zp.par". If you want to use a parameter file with a different name, say "my_zp_par.file", you would start start zp2 like this: 
unixprompt> zp2 filename.head my_zp_par.file
where filename.head is the name of your zp header file created by zp1. You do not have to have a namelist parameter file. If you don't have a parameter file, zp2 will use default values for all plotting parameters. The parameter file is used if you want to change the value of one or more plotting parameters from its default value. You can also, of course, change many plotting parameters interactively when running zp2. During an interactive session, if you want to save the current plotting parameter settings, type "W" (capital w) on the graphics screen: this creates a parameter file called "zp.par_out". So if you don't have a zp.par file, just start up zp2 and type "W". You can then edit/rename the zp.par_out file.

A zp parameter file comprises two namelists, called par1 and par2, each comprising a number of parameters. The par1 namelist generally contains parameters associated with choosing the data to be plotted; the par2 namelist parameters are generally associated with the look of the plotted data. Within each of the two namelists, you can specify the value of any valid namelist parameter. Parameters not listed in the namelist are automatically assigned default values.

Here is what a typical zp.par file looks like: 

  &PAR1
   plot_versus='tsno'  origin='dist'  gather='shot'
   az_distpm=0.000  distpm_dir=0  azimuth_mode=0  azimuth_divide=0.000
   red_velocity=8.000  dec_factor=1
   min_dist_km=-99999.000  max_dist_km=99999.000
   min_time_s=0.000  max_time_s=4.790
   min_az_deg=-360.000  max_az_deg=360.000
   min_tnofr=0  max_tnofr=0
   min_espn=1  max_espn=810
   first_trace=1  last_trace=810
   irev=1
   uncval=10,4,2,1.75,1.5,0
  &END
 
  &PAR2

   iagc=0  tagc=1.000  pagc=1.000
   xsp=0.000  ysp=0.000
   anno_word='    '  anno_int=-1  ansymbht=1.500  symbht=2.510
   title=''
   ititpos=0  imap=0  maplen=50.000
   mapfile='zp_map.dat'
  &END
The default values for par1 are specified in the file zp2_default.inc. The default values for par2 are specified in the file zp2_pdefault.inc. You can get help on any parameter by either looking in these files, or by running the utility code called "zp2_help", or by clicking on the following two links.
