WSClean version 2.10¶
Released 2020-07-15
WSClean 2.10 depends on IDG version 0.7 or newer.
Summary of changes: WSClean can now run on multiple nodes using MPI. Several new methods for calculating a-terms were added: position-delta screens, better kernel windowing, gridding with the VLA beam and joint deconvolution of multibeam/PAF systems (which was demonstrated using Apertif).
This is the last version that is released via SourceForge. Future development will move to GitLab: https://gitlab.com/aroffringa/wsclean.
Major & visible changes:
Support for distributed computing using MPI
Support for “position shift screens” (dldm-screens) during a-correction gridding
Support for joint deconvolution of PAF / multi-beam observations
More windowing options for a-correction kernels, defaults now to “raisen Hann”
The VLA beam has been implemented
Support imaging of multiple fields
Add parameter
-multiscale-max-scales
Restore source component models using
-restore-list
Bug fixes & other changes:
Properly weigh channels when averaging with user-set deconvolution channels.
WSClean could iterate infinitely when first multiscale scale is not 0
GCC 10 fixes
Improved error reporting
Fix inversion timing
