Figure 8 will not reproduce well when printed in black and white due
to the different colours used for each line. When converted to grayscale, most of these colours will look very similar and will be hard to distinguish, hence why we have added a note to the caption to encourage readers to access the online version. If you have an editable version of this figure please can you send it to us, or if you are able to change the line styles (e.g. use shades of black and grey and use dotted/dashed lines) so that they can be recognised in grayscale, please send us a revised version. If this is not possible, we can proceed with this version and include the note as shown.
