Confusion on units in hrv_frequency

[jinxrecchio]

Hello! I've read through the documentation on hrv_frequency as well as a few Issues/Discussions posts and seem to have found a few conflicting answers on the units for the hrv_frequency output. I've found answers stating that the absolute power output, which by default is normalized, is in both ms2 and ms2/Hz. Is this also affected by the interpolation_rate parameter in hrv_frequency? Or would the units be based on the initial sampling rate? For example, if your data is the default sampling rate of 1000, and you're using the default interpolation of 100, are the output values in ms2 or ms2/hz? What if you have an interpolation_rate of 10 or the Kubios default suggestion of 4? Would those affect the units on the output? Could that be why I've seen different answers? Any advice would be appreciated. Thanks!
