The image was created from Hubble data from proposals 12101: M. Postman (STScI); 9722: H. Ebeling (University of Hawaii); and 10493 and 10793: A. Gal-Yam (Weizmann Institute of Science, Israel).
ACS/WFC: F435W (B), F475W (g), F555W (V), F606W (V), F625W (r), F775W (I), F814W (I), and F850LP (z)
WFC3/IR: F105W (Y), F110W (YJ), F125W (J), F140W (JH), and F160W (H)
This image is a composite of separate exposures acquired by the ACS and WFC3 instruments. Several filters were used to sample various wavelengths. 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:
Blue: ACS/WFC F435W (B) + F475W (g) + F555W (V) + F606W (V) + F625W (r)
Green: ACS/WFC F775W (I) + F814W (I) + F850LP (z), and WFC3/IR F105W (Y) + F110W (YJ) + F125W (J)
Red: WFC3/IR F140W (JH) + F160W (H)
