  • The pipeline has been ported to work with CASA 5+ versions, and works with latest version available v5.4
  • It can calibrate spectral line data.
  • It can calibrate all frequency bands: C, L and K band.
  • Accepts pseudo wideband processing (C-band data from 4.5 to 7.5 GHz).
  • Pipeline can search for observatory logs of slewing antennas and flag off-source visibilities.
  • Multiprocessing CASA (mpicasa) working properly.
  • The weblog includes a summary page with real-time information of steps executed, main parameters and access to all processing and calibration parameters used.
  • Add-on script under development to self-calibrate sources processed with the pipeline.
  • Implemented automatic Lovell dropout scans detection and flagging.
  • The pipeline accepts models of the structure of the phase calibrators.
  • Added possibility to use any flux calibrator and to set the flux manually.
  • New autoflagging procedures (TFCROP, and optionally RFLAG) during calibration.
  • Use phase solution tables to flag calibrator visibilities.
  • More complete plots of calibration tables.
  • Pipeline can correct phase centre of sources, or generate new phase centres for other sources in the FoV.

The eMCP can do:

  • Import fits data and generate a summary weblog (basic information, uvplots, elevation, listobs, etc.).
  • Prepare MS: hanning, separate spectral line data, autoflag with aoflagger, a-priori and manual flags, average.
  • You can produce amplitude and phase plots against time and frequency and inspect them in the weblog.
  • Calibration of continuum data. Delay, bandpass, phase, phase jitter, amplitude, fluxscale, bandpass with spectral index.
  • Produces caltables plots and plots of corrected data (accessible via the weblog).
  • Two more runs of autoflagging (tfcrop using bandpass calibration, and rflag after calibration).

Additional features:

  • Can find best antennas to be use as refant.
  • Can deal with Lo drop out scans (not observing phase calibrator) by modifying the calibration tables.
  • Can use more than one bandpass calibrators.

CASA 5.1 and fringefit

This version breaks from versions v0.4 because it requires CASA v5.1+, and it is not compatible with CASA v4.7. Other changes are:

  • Support to use fringefit when it is available in CASA v5.3 (not used for the moment).
  • New aoflagger strategies.
  • Improved msinfo management.
  • Now it is possible to execute the pipeline from a CASA session.
