We present a systematic analysis of annular substructures in the 18 single-disk systems targeted in this survey. No dominant architecture emerges from this sample; instead, remarkably diverse morphologies are observed. Annular substructures can occur at virtually any radius where millimeter continuum emission is detected and range in widths from a few au to tens of au. Intensity ratios between gaps and adjacent rings range from near-","authors_text":"A. Meredith Hughes, Andrea Isella, Cornelis P. Dullemond, David J. Wilner, Erik Weaver, Jane Huang, John M.
