Clarification on Welch Method Parameters for HRV in NeuroKit2

[ThipkanlayaJaiaue]

Hello,

I am currently using NeuroKit2 for my research and would like to clarify how the Welch method is implemented in the library. Specifically, I have been trying to locate the details on the window length and window overlap parameters used, but I have not been able to find this information in the documentation or source code.

Could you please clarify the window length and window overlap parameters used in the Welch method for HRV computation in NeuroKit2?

Thank you for your time and for maintaining such a valuable tool for the research community.
