Pixelization and Dynamic Range in Radio Interferometry
W. D. Cotton, Juan M. Uson
This study investigates some of the consequences of representing the sky by a rectangular grid of pixels on the dynamic range of images derived from radio interferometric measureme…
Corrugations in the Disk of the Edge-On Spiral Galaxy IC2233
L. D. Matthews, Juan M. Uson
We recently reported the discovery of a regular corrugation pattern in the HI disk of the isolated, edge-on spiral galaxy IC2233. Here we present measurements of the vertical struc…
Beam squint and Stokes V with off-axis feeds
Juan M. Uson, W. D. Cotton
Radio telescopes with off-axis feeds, such as the (E)VLA, suffer from "beam squint" in which the two orthogonal circular polarizations sampled have different pointing centers on th…
Correcting direction-dependent gains in the deconvolution of radio interferometric images
S. Bhatnagar, T. J. Cornwell, K. Golap +1
Astronomical imaging using aperture synthesis telescopes requires deconvolution of the point spread function as well as calibration of instrumental and atmospheric effects. In gene…
