Who can tell me the reason why Re_tau=395?

Who can tell me the reason why Re_tau is chosen 395 in channelOodles tutorials?
I saw Eugene's thesis use this to compare the results with DNS of Kim 1987, BUT whose Re_tau is 180, not 395!!!

If I was wrong, then what is the reference of Re_tau=395? I cannot find the DNS database of Re_tau=395, I know it not.

Thank you

I think it comes from an unpublished work from Kim (1989), which data is available on ERCOFTAC website.

I see, I have downloaded the DNS data. Thank you for your attention.
