Text correction

In the published article, there was an error. The subscript on the numerator and denominator in formula 2 was written backwards.

A correction has been made to Preliminary, Signal propagation time simulation, Paragraph 2. This sentence previously stated:

$$t^m=\sum _{d=1}^{D-1}\left|\frac{\mathrm{\Delta }{z}_d}{s^{d+1}-s^d}\ln \left(\frac{s^{d+1}(1+\sqrt{{\text{ϒ}}_d^m})}{s^d(1+\sqrt{{\text{ϒ}}_{d+1}^m})}\right)\right|$$

The corrected sentence appears below:

$$t^m=\sum _{d=1}^{D-1}\left|\frac{\mathrm{\Delta }{z}_d}{s^{d+1}-s^d}\ln \left(\frac{s^d(1+\sqrt{{\text{ϒ}}_{d+1}^m})}{s^{d+1}(1+\sqrt{{\text{ϒ}}_d^m})}\right)\right|$$

The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
