Low-frequency part of the clutter in the spectrogram of the magnetic field #127

Step 1: Latest code?

Step 2: Describe your environment

Step 3: Describe the problem

Expected behavior

I would like to view the magnetic field spectrogram of the low-frequency portion using “Example_MMS_EBfields” for wavelet analysis.

Actual behavior

The magnetic field spectrogram has a lot of clutter in the 0.4-4hz range, even so much so that it's in every picture for every time period. I think this may not be an anomaly in the data itself, but is it possible that some specific parameters in the function irf_wavelet need to be modified when doing the Low frequency wavelet analysis. Have you encountered this and is there any solution?

Steps to reproduce:

fmin = 0.01; fmax = 10; %Hz Other settings are the same as in the example
