<name>DSND ionospheric parameter scaling</name>
<description>This is the collection of parameters analysed from HF sounder data using the DSND software collection. The analysis detects echoes and their direction of arrival and uses this data to retrieve
1. The standard ionospheric parameters at O, X and Z modes
2. NeXtYZ electron density profiles and parameters
3. Plasma irregularity and bulk velocity parameters</description>
