Tables and Figures
Table and Figure legends should be placed separately and consecutively after the References section. The total number of figures and tables should not exceed ten.
The Tables and then Figures themselves should then follow, and be consecutively numbered using Arabic numerals (1, 2, 3…). For initial submission, Tables and Figures can be included in the same file as the main text or be submitted separately and must be of sufficient clarity and resolution for peer review to be undertaken. If files are submitted separately, the submission system will automatically prepare a single PDF for review purposes, which can be verified during the submission process.
If your manuscript is accepted for publication, separate files for figures will need to be supplied. For the production process, figures must have a minimum resolution of 300 dpi for color and 600 dpi for monochrome.
