vis-r converts parametric radial surface-brightness profiles directly into model visibilities for radio-interferometric data using a Discrete Hankel Transform. It supports disks with one or more radial components, optional vertical scale height, and can include compact or Gaussian central sources or point sources. Model fitting can be performed using either the emcee sampler (ascl:1303.002) or a Stan (ascl:1801.003) backend, with options for independent astrometry per visibility dataset in the emcee implementation. This method enables fitting parametric radial models directly to visibility data without the need to generate full images.
