calculations

[BarbaraFroner]

Hi,

I was going through the tutorial and in the Fixing / editing the logs section I noticed that the water time above SRD is calculated as follows:

water_twt = 2.0*abs(water_depth + EGL_time) / water_vel

Shouldn't it instead be:

water_twt = 2.0*abs(water_depth) / water_vel  + EGL_time

Between the two there is a discrepancy in the results of roughly 40 ms.

Thanks!

That does indeed look like a bug, thank you! I have asked the author to look at it.

Thank you.

By the way, very informative tutorial! Especially for somebody non-geo and relatively new to logs like me.
