| About The Data | |
| Data Description | The image was created from Hubble data from proposal : S. Baum and C. O'Dea (Rochester Institute of Technology) and J. Stoke and F. Lo (Associated Universities, Inc.). Notes:The VLA data are from the National Radio Astronomy Observatory observation project TDEM0011: R. Perley, W. Cotton, and U. Rao (NRAO/AUI/NSF). These data were taken August 2010 through September 2011. Frequencies 4-9 GHz were measured. |
| Instrument | National Radio Astronomy Observatory VLA |
| Filters | C Band Low (4-6 GHz), C Band High (6-8 GHz), and X Band Low (8-9 GHz) |
| About The Image | |
| Color Info | This image is a composite of separate exposures acquired by the VLA. Several filters were used to sample various wavelengths/frequencies. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Red: VLA C Band Low (4-6 GHz) Green: VLA C Band High (6-8 GHz) Blue: VLA X Band Low (8-9 GHz) |
