Color: This image was originally black and white and measured brightness, multiplied by the distance to the stellar position squared. 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. The central dark spot in the release data is due to the NICMOS coronagraph, not due to a central clearing in the disk.
