Argo V2 build 42 is ready for download from this address :

I have added the possibility for the user to choose the wanted sampling frequency. Read the updated User Guide for details.
While at that, I discovered also a subtle bug, which could cause hangs in some circumstances.  Exterminated.

As usual, reports welcome.
