This image was created from HST data from proposal 10915: J. Dalcanton (University of Washington) et al. The science team comprises B. Holwerda and R. de Jong (Space Telescope Science Institute), W. Keel (University of Alabama, Tuscaloosa), and J. Dalcanton and B. Williams (University of Washington).
F475W (B), F606W (V), and F814W (I)
The image is a composite of separate exposures made by the ACS instrument on the Hubble Space Telescope. Three filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:
Blue: F475W (B)
Green: F606W (V)
Red: F814W (I)
