DP3 Changelog

Next release

Improvements

  • DP3 now requires EveryBeam v0.5.8

[6.0] - 2023-08-11

New features

  • Optional support for Sagecal (libdirac), if that is installed.

  • Re-using model visibilities in multiple steps (e.g. ddecal steps) is now possible through the ‘extradata’ feature.

  • Python bindings are thoroughly refactored; entire DP3 pipelines can now be constructed from Python.

  • DP3 now has some steps with increased performance specifically for the AARTFAAC instrument.

Improvements

  • Under the hood some casacore structures were replaced by xtensor structures, which may reduce memory usage.

  • Deprecate the use of FULL_RES_FLAGS. These are not written anymore.

  • DP3 now requires EveryBeam v0.5.1

  • Experimental use of AVX and XSIMD features to speed up various operations.

Bug fixes

  • Fix predicting sky components with negative n-value (further than 90 degrees from phase centre) - note that this bug did not affect the demix step.
