History of changes to the Version 3 (Year 2000) software: Sept 2, 1998: Bug in output of harmsss.lis (sss:station) corrected so station number would be correct. Also make column headings aligned. Sep 22, 1998: Minor corrections to typos in the manual. Nov 04, 1998: An error was found in Program DTDCNV.FOR (within \SLPR2\DIN). The program incorrectly searched for file \SLPRC\DIN\STAINFO.DIN. The path was corrected to \SLPR2\DIN\STAINFO.DIN. The title of plot program HOURYR was changed from "Hourly Residual Plot Program" to "Hourly Plot Program for Observed, Residual, and Predicted Files." Nov 13, 1998: Thanks to Bryan Ward of the Royal New Zealand Navy Hydrographic Office, who pointed out that the tidal analysis could not handle input from Port Nelson, which has roughly a 3.5 m tidal range during spring tides. A parameter in FITTIDE.FOR (/SLPR2/TIDE/SRC) was set such that when the difference between two successive hourly values exceeded 1 meter, the analysis would abort (assuming data in error). For the new version, this parameter was set to a value of 2500. The executable, FITTIDE.EXE, is available in this directory if you would like to have a version that handles extreme tidal ranges. Dec 28, 1998: The columns in file HARMsss.LIS (sss:station id) were mislabeled. The AL and GL should have been A and G. The last two columns, A and GNWCH are now correctly labeled AL and GL. The predictions are based on A and G, the same as the version 1.0 and 2.0 of this software. Jul 12, 2000: Program CHUNIT.FOR, which changes the units for a given file, was modified to allow crossover into a new century. The original Y2K version required one to run the program separately for each century. Aug 18, 2006: Bug in Filthr when more than 14 years run, would make single day value blank. Fixed. Also add FILTHR2 (in /src) that makes a second monthly output file with counts of missing days per month
