Large Figure Sets
The AAS journals now offers the option of publishing large sets of online-only figures in the electronic edition. For a recent example, see the Figure Set in the paper by Tommasin et al. in the The Astrophysical Journal. To facilitate submission of these large figure sets, the AAS has created a set of macros that should be used for marking up the figure set file name, caption, and label information in AASTeX. See the Figure Set documentation for more information.
