Sotomayor-Beltran, C.; Sobey, C.; Hessels, J. W. T.; de Bruyn, G.; Noutsos, A.; Alexov, A.; Anderson, J.; Asgekar, A.; Avruch, I. M.; Beck, R.; Bell, M. E.; Bell, M. R.; Bentum, M. J.; Bernardi, G.; Best, P.; Birzan, L.; Bonafede, A.; Breitling, F.; Broderick, J.; Brouw, W. N.; Brueggen, M.; Ciardi, B.; de Gasperin, F.; Dettmar, R.-J.; van Duin, A.; Duscha, S.; Eisloeffel, J.; Falcke, H.; Fallows, R. A.; Fender, R.; Ferrari, C.; Frieswijk, W.; Garrett, M. A.; Griessmeier, J.; Grit, T.; Gunst, A. W.; Hassall, T. E.; Heald, G.; Hoeft, M.; Horneffer, A.; Iacobelli, M.; Juette, E.; Karastergiou, A.; Keane, E.; Kohler, J.; Kramer, M.; Kondratiev, V. I.; Koopmans, L. V. E.; Kuniyoshi, M.; Kuper, G.; van Leeuwen, J.; Maat, P.; Macario, G.; Markoff, S.; McKean, J. P.; Mulcahy, D. D.; Munk, H.; Orru, E.; Paas, H.; Pandey-Pommier, M.; Pilia, M.; Pizzo, R.; Polatidis, A. G.; Reich, W.; Roettgering, H.; Serylak, M.; Sluman, J.; Stappers, B. W.; Tagger, M.; Tang, Y.; Tasse, C.; ter Veen, S.; Vermeulen, R.; van Weeren, R. J.; Wijers, R. A. M. J.; Wijnholds, S. J.; Wise, M. W.; Wucknitz, O.; Yatawatta, S.; Zarka, P.

ionFR calculates the amount of ionospheric Faraday rotation for a specific epoch, geographic location, and line-of-sight. The code uses a number of publicly available, GPS-derived total electron content maps and the most recent release of the International Geomagnetic Reference Field. ionFR can be used for the calibration of radio polarimetric observations; its accuracy had been demonstrated using LOFAR pulsar observations.

[ascl:2011.017] RRATtrap: Rotating Radio Transient identifier
Karako-Argaman, C.; Kaspi, V. M.; Lynch, R. S.; Hessels, J. W. T.; Kondratiev, V. I.; McLaughlin, M. A.; Ransom, S. M.; Archibald, A. M.; Boyles, J.; Jenet, F. A.; Kaplan, D. L.; Levin, L.; Lorimer, D. R.; Madsen, E. C.; Roberts, M. S. E.; Siemens, X.; Stairs, I. H.; Stovall, K.; Swiggum, J. K.; van Leeuwen, J.

RRATtrap is a single-pulse sifting algorithm to identify Rotating Radio Transients (RRATs) and transients using output from the PRESTO (ascl:1107.017) routine single_pulse_search.py. It can be integrated into pulsar survey data analysis pipelines and, in addition to finding RRATs, it can also identify Fast Radio Bursts.

[ascl:2309.005] DeepGlow: Neural network emulator for BOXFIT
Boersma, Oliver M.; van Leeuwen, Joeri

The feed-forward neural network DeepGlow emulates BOXFIT (ascl:2306.059) simulation data of gamma-ray burst (GRB) afterglows. The package provides an easy interface to generate GRB afterglow spectra and light curves mimicking those generated through BOXFIT with high accuracy. The code used to generate the training data and to train the neural networks is also included.

[ascl:2504.025] RFIClean: Mitigation of periodic and spiky RFI from filterbank data
Maan, Yogesh; van Leeuwen, Joeri; Vohl, Dany

RFIClean excises periodic RFI (broadband as well as narrow-band) in the Fourier domain, and then mitigates narrow-band spectral line RFI as well as broadband bursty time-domain RFI using robust statistics. Primarily designed to efficiently search and mitigate periodic RFI from GMRT time-domain data, RFIClean has evolved to mitigate any spiky (in time or frequency) RFI as well, and from any SIGPROC filterbank format data file. RFIClean uses several modules from SIGPROC (ascl:1107.016) to handle the filterbank format I/O.
