Dear colleagues,

I am currently performing Distribution of Relaxation Times (DRT) analysis on Electrochemical Impedance Spectroscopy (EIS) data, but I am encountering difficulties in selecting the appropriate regularization factor.

The regularization factor significantly influences the results:

• Higher regularization values (e.g., 0.1) lead to smoother plots but might obscure important features.
• Lower regularization values (e.g., 0.00001) reveal more peaks but risk amplifying noise and introducing artifacts.

In the attached image, you can see how the results vary between these two extremes.

My Questions:

I would greatly appreciate any insights, experiences, or resources you can share to help refine my analysis.

Thank you in advance for your valuable input!
