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	HST>WFC3/UVIS and National Radio Astronomy Observatory VLA
Exposure Dates	October 8, 2012, Exposure Time: 1 hour
Filters	WFC3/UVIS: F606W (V) and F814W (I) VLA: 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 Hubble's WFC3 instrument and 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: Orange: F814W (I) Blue: WFC3/UVIS F606W (V) + VLA X Band Low (8-9 GHz) Green: VLA C Band High (6-8 GHz) Red: VLA C Band Low (4-6 GHz)
