DSToolbox aims at creating a framework for the analysis of Dynamic Stall based on experimental data. The experimental data might be produced using an airfoil describing different type of motion, especially pitching and ramping up.

Location of Kirchhoff lift CNf peak is discretized due to added mass noise #16

Noise related to added mass is making the CNf = CNk+CNI curve wobbly, which in turn makes the location of the maximum CNf wrongly identified to a noise peak.

In turn, the scatter plot with all peak locations is discretized.

After using smooth derivatives algorithm the result is better
