Correcting Ionospheric Faraday Rotation for the VLA and MeerKAT
Richard A. Perley, Bryan J. Butler, Eric W. Greisen +3
We report here on studies to determine the accuracy of estimated corrections of Ionospheric Faraday Rotation Measure (IFRM) using observations of the Moon with the Very Large Array…
Tricolour: an optimized SumThreshold flagger for MeerKAT
Benjamin V. Hugo, Simon Perkins, Bruce Merry +2
We present Tricolour, a package for Radio Frequency Interference mitigation of wideband finely channelized MeerKAT correlation data. The MeerKAT passband is heavily affected by int…
Third-Generation Calibrations for MeerKAT observation
V. Parekh, R. Kincaid, B. Hugo +2
Superclusters and galaxy clusters offer a wide range of astrophysical science topics with regards to studying the evolution and distribution of galaxies, intra-cluster magnetizatio…
Xova: Baseline-Dependent Time and Channel Averaging for Radio Interferometry
Marcellin Atemkeng, Simon Perkins, Jonathan Kenyon +2
Xova is a software package that implements baseline-dependent time and channel averaging on Measurement Set data. The uv-samples along a baseline track are aggregated into a bin un…
The LOFAR Two Meter Sky Survey: Deep Fields, I -- Direction-dependent calibration and imaging
C. Tasse, T. Shimwell, M. J. Hardcastle +29
The Low Frequency Array (LOFAR) is an ideal instrument to conduct deep extragalactic surveys. It has a large field of view and is sensitive to large scale and compact emission. It…
MeerKATHI -- an end-to-end data reduction pipeline for MeerKAT and other radio telescopes
Gyula I. G. Józsa, Sarah V. White, Kshitij Thorat +13
MeerKATHI is the current development name for a radio-interferometric data reduction pipeline, assembled by an international collaboration. We create a publicly available end-to-en…
The MeerKAT Telescope as a Pulsar Facility: System verification and early science results from MeerTime
M. Bailes, A. Jameson, F. Abbate +72
We describe system verification tests and early science results from the pulsar processor (PTUSE) developed for the newly-commissioned 64-dish SARAO MeerKAT radio telescope in Sout…
Field sources near the southern-sky calibrator PKS B1934-638: effect on spectral line observations with SKA-MID and its precursors
I. Heywood, E. Lenc, P. Serra +8
Accurate instrumental bandpass corrections are essential for the reliable interpretation of spectral lines from targeted and survey-mode observations with radio interferometers. Ba…
Primary beam effects of radio astronomy antennas -- II. Modelling the MeerKAT L-band beam
K. M. B. Asad, J. N. Girard, M. de Villers +12
After a decade of design and construction, South Africa's SKA-MID precursor MeerKAT has begun its science operations. To make full use of the widefield capability of the array, it…
Faceting for direction-dependent spectral deconvolution
C. Tasse, B. Hugo, M. Mirmont +7
The new generation of radio interferometers is characterized by high sensitivity, wide fields of view and large fractional bandwidth. To synthesize the deepest images enabled by th…
