• Add support for primary beam correction (MeerKAT only).


  • Add extra FITS headers to the output; particularly those needed to compute Doppler corrections.
  • Improve performance when loading data from katdal datasets.
  • Add script to generate a video from FITS files.


  • Use direct prediction for the measurement equation, rather than FFT and degridding. This could potentially be slightly more accurate, although the images are not noticeably different. The old behaviour can be enabled with --degrid, which could be faster if there are very large numbers of CLEAN components.
  • Fix some bugs that could cause CUDA errors.
  • Fix a bug that would cause a crash for some image sizes.
  • A very small correction to parallactic angle calculations.
  • More efficient loading of katdal datasets.


This is the first versioned release.
