Millimetre continuum images for the 10 systems in the REASONS observing programme where a belt was not detected or significantly resolved, ordered by source RA. North is up, East is left. Bars indicate a physical scale of 50 au, and ellipses represent the synthesized beam of the observations. Images were obtained with the CLEAN algorithm as described in Sect. 3, with weighting parameters, resulting RMS noise levels and beams listed in the tables available on ZENODO (see Data availability section). All images are in a linear colour scale, stretching from 0 (black) to the maximum intensity of the image. Contours are set at [−4, −2, 2, 4, ..] times the RMS noise level of each image.
