Why is MSf characterised as "short period"?

[Remko Scharroo]

In prediction.c, line 1427 the MSf is classified as a short-period tide. That is incorrect. Even though it stems from the difference between M2 and S2 frequencies, it is actually a long-period tide, with a period of 14.77 days. Hence, I suggest it is classified as long-period instead.

This at least caused problems to me when I was determining the short- and long-period tides separately.

Thank you for your feedback. It is corrected and published in version 2.9.3.
