ACS/WFC: F435W (B), F606W (V), F775W (I), F814W (I), and F850LP (z)
WFC3/IR: F105W (Y), F125W (J), and F160W (H)
This image is a composite of separate exposures acquired by the ACS and WFC3/IR instruments. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image from the eight different filters used by the two instruments grouped as follows:
Blue: ACS/WFC F435W (B) + F606W (V)
Green: ACS/WFC F775W (I) + F814W (I) + F850LP (z)
Red: WFC3/IR F105W (Y) + F125W (J) + F160W (H)
