Footnotes to a table should be indicated by lower-case letters in parentheses and typed directly under the table. 4.9 Figures 4.9.1 General remarks Figures will be printed in black and white unless special circumstances demand the use of color. Every figure must be referred to in the text. Figures must be submitted in sizes that do not exceed the size of the manuscript paper. If they are smaller than the manuscript paper, they are to be pasted onto separate pages.
All figures are to be numbered with Arabic numerals in the sequence in which they are cited.
Every figure must be accompanied by a legend that begins with, for example, Figure 5. Legends are not to be typed under the figures, but should be collected on separate pages. Particular care should be taken to ensure that figures reporting data are unambiguously labeled with regard to units and, in their legends, provide adequate information about the conditions under which the data were obtained. The quality of the figures should be such that they can be reproduced directly after reduction to 85 mm width. Numbers, letters and symbols inscribed must be large enough to be still 1.5 mm high after the figure has been reduced to the printing format.
