About the Data
Data Description:

The Hubble image was created from HST data from proposal 9796: J. Miller (University of Michigan), G. Fabbiano and A. Zezas (Harvard-Smithsonian Center for Astropysics), P. Kaaret (University of Iowa), J. Grindlay (Harvard University), A. Kong (Massachusetts Institute of Technology), A. King (University of Leicester, UK), M. Ward (University of Durham, UK), V. Kalogera (Northwestern University), M. Krauss (Massachusetts Institute of Technology), M. Garcia (Harvard-Smithsonian Center for Astropysics).

The science team is composed of A. Pellerin and M. Meyer (STScI), J. Harris (Stewart Observatory), and D. Calzetti (STScI).

Note: Other Hubble ACS data (proposal 9494; PI: P. Padovani) and ground-based data (VLT; H. Boffin) were used to fill in the undithered chip gap. The below informaton contained within this section pertains to data from proposal 9797 only.
Instrument: ACS/WFC
Filters: F435W (B), F555W (V), F814W (I)
Exposure Date(s): November 22, 2003 and February 22, 2004
Exposure Time: 2.8 hours
About the Image
Image Credit: NASA, ESA, and A. Pellerin (STScI)
Release Date: January 10, 2007
Color:

This image is a composite of many separate exposures made by the ACS instrument on the Hubble Space Telescope using several different filters. Two filters were used to sample broad wavelength ranges. One filter was used to sample narrow wavelength emission. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:

F435W (B) blue
F555W (V) green
F814W (I) red
