MeqTrees
MeqTrees is a software system for the calibration and simulation of radio telescopes, especially aperture synthesis arrays. The user normally interacts with the system through a GUI, the MeqBrowser; a screenshot of the browser is shown in the figure below. 
MeqTrees was originally developed for the purpose of LOFAR calibration. The montage below shows an example of calibration of a LOFAR test station observation using shapelets to quantify the image structure of Cass A.
Some MeqTimba starting points:
The DocumentationProject. All system documentation should appear here eventually, and new stuff should be put here to begin with.
Building the system: BuildingTimba, BuildingTimba/CommonProblems and BuildingTimba/Rebuilding.
Various ConfusingErrors and what they may mean.
For developers: UsingSvn (and the no-longer-relevant UsingCvs page).
Other new pages: AxisPolicy,FrameWorks/StandardContracts, PrivateFunction, StridedIterators, Functionals, SolverIssues, SmearingIssues, GeneralFunklet, TreeDefinitionLanguage, StreamControl, UvBricks, LocalSkyModel, TiledSolutions, SpidDiscovery, Operation343TreeDefinitionLanguage, MajorLoop.
Note to page authors: I suggest we use the front page only for the most general stuff, and for documents pertaining to ongoing discussions. Most new pages belong in the DocumentationProject, so please add a permanent link there, and a small item to News & Announcements below.
