Constellation window.
The colour scale placed at the left side indicates the signal quality in a
qualitative way by a gradation of colours proportional to the density of
symbols concentrated in a given area. The colour scale ranges from black
(no symbols) to red (highest density).
Greater dispersion of the symbols indicates higher noise level or worse
signal quality signal. If there is symbols concentration with respect to the
full grid (see advanced menu for types of grid) this is indicative of good
ratio signal/noise or absence of problems.
