About the Data

Data Description: The Hubble optical image was created from HST data from proposal 10452: S. Beckwith (STScI), R. Kennicutt, Jr. (University of Cambridge), and H. Bond, C. Christian, L. Frattare, F.

Color: 	This image, which was obtained by aligning data from both the NICMOS and ACS detectors and dividing the NICMOS brightness values by the ACS values, was originally black and white. These brightness values were translated into a range of reddish hues. Such color "maps" can be useful in helping to distinguish subtly varying brightness in an image.
