A second optional parameter can be used to pass the name of a configuration file. This file must be located in ~/etc e.g. ~/etc/params_Hawaii.cfg . If no optional parameter is supplied, the configuration is read from ~/etc/params.cfg .
Visualizes backscatter spectra from raw data (.SORT), i.e. vs. range and direction.
Reads all information needed from the header (first 512 bytes of data file).
The following box shows a typical output generated by Plott_WERA16_SORT:

Graphics
output can be generated for each selected range cell and direction:
When standing in the center of the array, ant.1 to the left, ant. 16 to the
right, looking at the sea, the direction 90 degrees off the array direction
refers to zero degrees; to the left of this line the sign is negative, to the
right the sign is positive.
The example shows a backscatter spectrum about 24 km off the WERA site
at Kaena. Two strong first-order peaks can be seen with a slight shift to
higher frequencies relative to the Bragg lines (in red). The second-order
bands can also be identified left and right of the two first-order peaks.
The location of the harmonic peak (in blue) and the corner reflection peak
(in green) is also shown. The horizontal red line markes the noise level
of the spectrum.
