This script plots the output of a Point-to-Point prediction. Signal to Noise (SNR), Reliability (REL), Maximum Usable Frequency (MUF) or Received Signal Strength (S DBW) may be plotted. The application supports time shifting of the lower (GMT)

Refer to the man page for details.

This script plots the output of VOAARea predictions (.VGx files). Signal to Noise (SNR), Reliability (REL) or Maximum Usable Frequency (MUF) may be plotted. To produce correct type of input projection data files, the projection type flag in the input file's GRIDSIZE card must be set to '1', i.e.

Gridsize : 59 1

See the man page for details.
