The On The Fly Imaging Technique
J. G. Mangum, D. T. Emerson, E. W. Greisen
The On-The-Fly (OTF) imaging technique enables single-dish radio telescopes to construct images of small areas of the sky with greater efficiency and accuracy. This paper describes…
The 74MHz System on the Very Large Array
N. E. Kassim, T. J. W. Lazio, W. C. Erickson +7
The Naval Research Laboratory and the National Radio Astronomy Observatory completed implementation of a low frequency capability on the VLA at 73.8 MHz in 1998. This frequency ban…
Representations of spectral coordinates in FITS
E. W. Greisen, M. R. Calabretta, F. G. Valdes +1
Greisen & Calabretta describe a generalized method for specifying the coordinates of FITS data samples. Following that general method, Calabretta & Greisen describe detailed conven…
Representations of celestial coordinates in FITS
Mark R. Calabretta, Eric W. Greisen
In Paper I, Greisen & Calabretta (2002) describe a generalized method for assigning physical coordinates to FITS image pixels. This paper implements this method for all spherical m…
Representations of world coordinates in FITS
Eric W. Greisen, Mark R. Calabretta
The initial descriptions of the FITS format provided a simplified method for describing the physical coordinate values of the image pixels, but deliberately did not specify any of…
