WSClean Version 1.1¶
Released 2014-04-23
This version introduces new features including a wideband deconvolution method, and fixes quite a few bugs.
Changes:
New dependency: GSL and CBLAS are now required to build WSClean.
New feature: Cleaning channels joinedly with cmdline parameter:
-joinchannels
. This performs peak finding in the sum over all output channels, but subtracts components independently from the channels.New feature: Option to grid weights once for all output channels (
-mfsweighting
).New feature: When spectral imaging (with
-channelsout
), a weighted MFS image will be created.New feature: Direct imaging of Stokes IQUV, and possibility to clean joinedly over these too (requested by O. Smirnov, SF #2).
New feature: Support imaging specific polarizations (rr / Q / ..) in measurement sets with circular polarizations.
New feature: Specify absolute memory limit instead of relative limit (
-absmem
), requested by M. Bell.New feature: Implemented options -minuvw and -maxuvw to set range of baselines to be gridded.
Syntax change: explicit option for performing joined-polarization cleaning (
-joinpolarizations
), no longer the default.Change: When imaging >= 4 polarizations, reorder by default.
Bugfix: Fixing some valgrind errors and a possible segmentation fault.
Bugfix: ‘make install’ does not work (reported by G. Molenaar, SF #1).
Bugfix: With spectral imaging, the uvw are not correctly divided by lambda, leading to incorrectly scaled images.
Bugfix: Problem with
-smallinversion
and used memory.Bugfix: PartitionedMS handler does not handle an invalid WEIGHT_SPECTRUM column (reported by I. Heywood).
Bugfix: When reordering an MS, end with writing reordered model data back to measurement set, so that self-cal etc is still possible when using Cotton-Schwab cleaning.
Bugfix:
-interval
parameter does not work properly.Bugfix: Documentation for
-pol
parameter is out-dated (reported by O. Smirnov, SF #3).Bugfix: Remove temporary image files
