Hi Dimitri,

Well try it and let yo know. Thanks!

Hi Phil,

It is not implemented, but in src/specfem2D/prepare_color_image.F90 if
you replace

   ! horizontal min and max coordinates of the image
   xmin_color_image_loc = minval(coord(1,:))
   xmax_color_image_loc = maxval(coord(1,:))

   ! vertical min and max coordinates of the image, slightly increase it
to go beyond maximum topography
   zmin_color_image_loc = minval(coord(2,:))
   zmax_color_image_loc = maxval(coord(2,:))

with the min and max that you want it will probably work (please let us
know).

Thanks,
Dimitri.
