Color and Filters: 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:
ACS/WFC F435W(B)+F475W(g)+F555W(V)+F606W(V)+F625W(r) blue
ACS/WFC F775W(I)+F814W(I)+F850LP(z)
WFC3/IR F105W(Y)+F110W(YJ)+F125W(J)
green
WFC3/IR F140W(JH)+F160W(H) red
Orientation/Scale: Compass and Scale Image of MACS J0647+7015
