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…
Statistical discrimination of RFI and astronomical transients in 2-bit digitized time domain signals
Gelu M. Nita, Aard Keimpema, Zsolt Paragi
We investigate the performance of the generalized Spectral Kurtosis (SK) estimator in detecting and discriminating natural and artificial very short duration transients in the 2-bi…
Baseline-dependent sampling and windowing for radio interferometry: data compression, field-of-interest shaping and outer field suppression
M. Atemkeng, O. Smirnov, C. Tasse +4
Traditional radio interferometric correlators produce regular-gridded samples of the true -distribution by averaging the signal over constant, discrete time-frequency intervals…
The SFXC software correlator for Very Long Baseline Interferometry: Algorithms and Implementation
A. Keimpema, M. M. Kettenis, S. V. Pogrebenko +13
In this paper a description is given of the SFXC software correlator, developed and maintained at the Joint Institute for VLBI in Europe (JIVE). The software is designed to run on…
