CASA-4.7 Release Planning

Target Feature Freeze Date: 1 Aug 2016

tClean:

• VI/VB2 Integration (scratchless behavior)
• Allow imaging of partially flagged correlations (at least things like imaging stokes I when only RL or LR are flagged... ).
• Stokes Q, U, V images standalone
• MakePB C++ integration
• pbcor and wideband pbcor in c++
• Threaded Gridder Generalization (May be more than 1 cycle)
• Memory usage and automated heuristics
• Tool interface normalization (using lists)
• Task data selection when vis specifies a list of data sets.
• Time estimator (Flagging / tClean)
• Iterative Auto-masking

Refactoring and Integration with VI/VB2

• SetJy
• uvcontsub
• statwt

Preparation for pipeline polarization

Tool / Infrastructure

• Update / clean up, removal of ms-selector
• VI/VB2 in Calibration (completion)
• Modularization of TVI Interface
• Intent Selection in virtual models
• Enable OTF Hann Smoothing in Calibration Solvers

Performance / Cluster

• Pipeline HPC (Imaging)
• C++ MPI For tClean
• Resource management inside of parallel operations
• Create symbolic links for the sub-tables inside the Sub-MSs of a Multi-MS
• Move mstransform based utilities to primary production —> cvel2
• Allow combination of SPWs with different number of channels (either originally or selection) in cvel2

Image Analysis

• Image Moments refactor
• Continued UVFits issues.
• IA Logging
• Allow && operator on masks w/ stretching if required.
• Remove constraint that ellipsoid much be inside lattice

Single Dish: (full targets list at NRAO JIRA)

  • support calibration of fast-scanning observations (including spline interpolation and ephemeris correction of pointing direction in edge detection)
  • gain calibration of double-circle scans
• MS transition
  • use of line finder in tsdfit
  • sinusoidal fitting
  • polarization average
  • support averaging in tsdfit
  • clipping in imaging
  • side band separation
  • output visibility to ascii files
• Nobeyama support
  • NOSTAR -> MS filler
• Plotter extension
  • proto-type task of profile maps
  • plotter to support interactive operation

plotMS
