CASA, the Common Astronomy Software Applications for Radio Astronomy
THE CASA TEAM, Ben Bean, Sanjay Bhatnagar +46
CASA, the Common Astronomy Software Applications, is the primary data processing software for the Atacama Large Millimeter/submillimeter Array (ALMA) and the Karl G. Jansky Very La…
CASA on the fringe -- Development of VLBI processing capabilities for CASA
Ilse M. van Bemmel, Mark Kettenis, Des Small +14
New functionality to process Very Long Baseline Interferometry (VLBI) data has been implemented in the CASA package. This includes two new tasks to handle fringe fitting and VLBI-s…
A probabilistic approach to phase calibration: I. Effects of source structure on fringe-fitting
Iniyan Natarajan, Roger Deane, Ilse van Bemmel +6
We propose a probabilistic framework for performing simultaneous estimation of source structure and fringe-fitting parameters in Very Long Baseline Interferometry (VLBI) observatio…
SYMBA: An end-to-end VLBI synthetic data generation pipeline
F. Roelofs, M. Janssen, I. Natarajan +203
Realistic synthetic observations of theoretical source models are essential for our understanding of real observational data. In using synthetic data, one can verify the extent to…
First M87 Event Horizon Telescope Results. II. Array and Instrumentation
The Event Horizon Telescope Collaboration
The Event Horizon Telescope (EHT) is a very long baseline interferometry (VLBI) array that comprises millimeter- and submillimeter-wavelength telescopes separated by distances comp…
CASA on the fringe: VLBI data processing in the CASA software package
Ilse van Bemmel, Des Small, Mark Kettenis +3
In recent years new functionality for VLBI data processing has been added to the CASA package. This paper presents the new CASA tasks 'fringefit' and 'accor', which are closely mat…
