Africanus IV. The Stimela2 framework: scalable and reproducible workflows, from local to cloud compute
Oleg M. Smirnov, Sphesihle Makhathini, Jonathan S. Kenyon +4
Stimela2 is a new-generation framework for developing data reduction workflows. It is designed for radio astronomy data but can be adapted for other data processing applications. S…
Fast algorithms to approximate the position-dependent point spread function responses in radio interferometric wide-field imaging
M. Atemkeng, O. Smirnov, C. Tasse +2
The desire for wide-field of view, large fractional bandwidth, high sensitivity, high spectral and temporal resolution has driven radio interferometry to the point of big data revo…
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…
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…
Primary beam effects of radio astronomy antennas: I. Modelling the Karl G. Jansky Very Large Array (VLA) L-band beam using holography
K. Iheanetu, J. N. Girard, O. Smirnov +5
Modern interferometric imaging relies on advanced calibration that incorporates direction-dependent effects. Their increasing number of antennas (e.g. in LOFAR, VLA, MeerKAT/SKA) a…
Kliko - The Scientific Compute Container Format
Gijs Molenaar, Spheshile Makhathini, Julien N. Girard +1
Kliko is a Docker-based container specification for running one or multiple related compute jobs. The key concepts of Kliko are the encapsulation of data processing software into a…
