            <Description> Density values (and quality)  are related to sounding operations.
The density value is calculated from an algorithm for resonance recognition, which cannot take account of all level of information available to the experimenter.    
Quality parameter can take 2 values: 3 for density extraction by a semi-
automatic pipeline (standard quality) and 4 for manual processing (high quality).
Although all density values given by the semi-automatic pipeline are considered
as reliable, a manual extraction will always give better estimates. All the density
values provided by the CSA archive may be considered as reliable values. This is
because all the ambiguous density values have already been filtered during the
extraction process (manually or by the software).
