Application of continuous corrections in widefield imaging obtained with the IDGCAL calibration method
Sebastiaan van der Tol
Image Domain Gridding (IDG) is an efficient method to evaluate A-projection, a method for correcting for direction dependent effects (DDEs) in radio astronomical imaging. The corre…

Direction-dependent calibration with image-domain gridding
Sebastiaan van der Tol, Sarod Yatawatta, Bram Veenboer +1
Wide-field images made by radio interferometers are invariably affected by direction-dependent systematic effects such as the ionosphere or the beam pattern. Calibration along a se…
