WSClean Version 1.0

Released 2014-03-15

This is the first public WSClean version. The features currently supported:

• Fast wide-field imaging

• Hogbom cleaning & Cotton-Schwab cleaning

• Joined-polarization cleaning (peak finding in \(xx^2+xy^2+yx^2+yy^2\))

• W-snapshot imaging

• Most common weighting modes (uniform, Briggs’, natural, super and sub-pixel weighting)

• Adjustable antialising kernel

• All important operations are multi-threaded

A paper has been submitted that shows WSClean’s accuracy is at least equal to the w-projection imaging in CASA, and sometimes even better, with a considerable faster imaging time when large w-values are involved.
