Convert PtNorms file with surface arrival times into an ascii list of surface arrival times on a rectangular grid of nx by ny points with increments dx and dy. If the optional help= flag is not coded, then all of the arguments, dx, dy, nx, ny, in, and out must be specified.

• help= causes a help message to be printed. The "help" information is also printed if any of the flags "-h ? or -help" are present.
• in= input_PtNorms_file identifies the input PtNorms file
• out= output_ascii_list identifies the output list
• dx= delta_x specifies the increment in the x direction to be used in converting values of the x coordinate from the PtNorms file into indices in the x direction for the output "grid".
• dy= delta_y specifies the increment in the y direction to be used in converting values of the y coordinate from the PtNorms file into indices in the y direction for the output "grid".
• nx= number_of_x_positions specifies the number of positions in the x direction of the output grid.
• ny= number_of_y_positions specifies the number of positions in the y direction of the output grid.
