The author would like to amend the incorrectly labelled segments of the scale bar he used in Figure 1 of the above article. Segments on the scale bar should read 100, 200 and 300 rather than 10, 20 and 30. The author would also like to remove from the scale bar, the ratio scale, which is reported to be 1:50,000, because this is inaccurate. The corrected figure is published on the following page.
