Analyzing
Click Analyse to initiate the iteration process.
Once clicked, the system continuously displays the progress of the tidal analysis, both as
a thermometer on this screen and by displaying an extra graph in the main screen in the
Analysis Layer - see below. The window contains a vertical thermometer which displays
the RMS Error and the horizontal black bar which displays the progress of the iteration.
The information box in the lower window area gives you the error which has been
attained.
During analysis, a trial graph is continuously written to the analysis layer, and as time
progresses the graph which emerges becomes increasingly similar to the working layer.
The analysis graph below is shown in blue, while the original data is shown in yellow.
When the iteration condition has been attained the iterative process stops. Alternatively
you can click the Analyse button (now labelled Stop) to halt the process.
The information box, a the lower centre of the tidal analysis window, shows the R.M.S.
error as 33.7mm. This is calculated for all of the points in the Working Layer. You can
also view the harmonic constants produced by accessing the menu option View>Analysis
Constants .
To conclude the Analysis session, leaving the harmonic constants in memory, you
should click the OK button. Click Cancel to exit the session without leaving the harmonic
