# History file 'prem-grd.h' to generate PostScript files with
# the sections across the model PREM displaying the velocities
# and indices of complex blocks, respectively
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# Input files required:
 #chk.pl: "model/prem/" "prem-mod.dat"
 #chk.pl: "model/prem/" "prem-grd.dat"

# Data for gridding and plotting:
  MODEL='prem-mod.dat'
  N1=640    N2=640
  D1=10.    D2=10.
  O1=0.     O2=0.
  VMIN=0.     # Zero velocity is rendered as undefined.
  VSIGN=-1    # Minimum velocity (water) is blue and inreases through
              # green to yellow and red (the default is opposite).

# Programs to run:
  grid:  'prem-grd.h' 'prem-grd.dat' /               # Gridding velocities
  grdps: 'prem-grd.h' 'prem-vel.out' 'prem-vel.ps' / # Plotting velocities
  grdps: 'prem-grd.h' 'prem-icb.out' 'prem-icb.ps' / # Plotting block indices

# ======================================================================

# List of output PostScript figures:
# prem-vel.ps: Section across the model PREM, displaying the velocities
# prem-icb.ps: Section across the model PREM, displaying the indices
#              of complex blocks
