Caption: Figure 13.

Same as Figure 8 but for TIC 289822938 (upper panel) and TIC 352830705 (lower panel). Both targets produce prominent anticorrelated ETVs, although the sparse coverage makes estimating the outer period difficult. For illustrative purposes, the lower panel shows a double sine fit to TIC 352830705 with a potential outer period of about 1700 days.
