An interferometric imaging package
Bug corrected in the distributed version 4.0 (and beyond):
PIPELINE /MODE SURVEY was not working properly when strong lines were present in spectral window, because line subtracting was improperly done, and contaminated the full bandwidth.
Note that the PIPELINE /MODE ALL with NO Catalog was similarly affected, whereas other modes (including PIPELINE /MODE ALL with a Catalog) were not affected by this issue.
Bug corrected in the distributed version 4.0 (and beyond):
Description: PIPELINE crashes (in Survey mode): Continuum image could not be created.
This was due to incorrect channel flagging when a strong/broad line is present close to the edge of a frequency band. In some cases, too many (if not all) channels were flagged, resulting in no continuum channels.
Recommandation: you may test first the line identification with the UV_PREVIEW command before starting the imaging process with the PIPELINE (adjusting TAPER, SMOOTH and CLIP variables may help, if the problem persists in exotic cases).
The new version (4.0-02, April 2024) is now fully available for installation on Linux, Windows and MacOs (including a MacPorts package).
The new release (3.9.11, January 2024) is now fully available, including an updated MacPort package for installation under MacOs.
