When you select one of the radio buttons at the top of the browser page:
and click on the Send for Processing button, the text
contained in the box below the buttons will be transmitted to
the U.of Waterloo website for processing. You can make changes to
the text box contents. One can delete a fatigue data point by
placing a "#" in the first position of a data line; or one can
add a bunch of new data lines, and then re-transmit the file.
Go ahead and try it.
After the transmitted file is processed at the remote site,
a graph and some text are returned to your browser.
Towards the bottom of the returned page you will see a section of
text that constitutes the "traditional" Coffin-Manson-Basquin fitted
file. These fitted points are from the black and green lines that
go through the data points in the above graph.

Often the "traditional" fit method will not actually fit all
parts of the raw data plot. Thus manual adjustments are made
to the automatic fit output, to better model the characteristics
of the raw data file. The Fitted data file can be processed
using the same Send for Processing button, but the results do not
really have any useful meaning. The file is just provided to
users who may wish to adjust the fitted file for their own needs.
