Warning while computing DTT

[gmsilveira]

Hello,
I need some advice as I am getting multiple warnings as below:
obspy/lib/python3.10/site-packages/msnoise/s06compute_dtt.py:141: RuntimeWarning: divide by zero encountered in double_scalars
wstd = np.sqrt(np.sum(w * (d - wavg) ** 2) / ((N - 1) * np.sum(w) / N))

Can it be related to the MWCS and step? I'm following the recommendation and using MWCS length about 1.2 to 1.5 twice the highest period.

I found a question on the same issue, but I could not find the xtol in api.py (located at anaconda3/envs/obspy/lib/python3.10/site-packages/msnoise/)

Many, many thanks!
