How to see used harmonic constants with hatyan are up to date?

[meteorkees]

Ref previous issue running hatyan; When running in a virtual env I have no issues... My first try was running the example script with Thonny. This did not work out.

Running within the virtual environment I get the expected returns.
You can close/remove the other issue.

remaining my search for the 94 harmonic analyse constants. The text file VLISSGN_ana.txt prints 94 NCON but on top of the page it shows "geldig voor jaar 2015".

The 94 NCON; are they up tot date?
Can I run this script to predict tide for the next, say 30/40 years...?

Thx,
Kees
