Modified blackbody results: Disc models of HIP 22263, HIP 62207, and HIP 72848 (left to right) at 100 μm. For each target the observation, ring model, convolved model (including star) and residual image (observed – convolved) are shown (top to bottom). Scalebar units are × 10⁴ Jy/arcsec² for the observed and convolved images, but in units of signal-to-noise for the residual image. The HIP 62207 convolved image includes a background source not shown in the disc model image. Orientation is north up, east left and the image pixel scale is 1′′.
