| Instrument | HST>ACS/WFC |
| Exposure Dates | May 29 - July 8, 2010 |
| Filters | F475W (g), F625W (r), F775W (i), F814W (I), and F850LP (z) |
| About The Image | |
| Color Info | Note: The release image is a composite of the F814W (I) data from proposal 11710, taken May 29 - July 8, 2010, and F475W (g), F625W (r), F775W (i), and F850LP (z) data from proposal 9289, PI: H. Ford (JHU), taken June 12 - 21, 2002. This image is a composite of separate exposures acquired by the ACS instrument on the Hubble Space Telescope (HST). Several filters were used to sample broad wavelength ranges. 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: F475W (g)Green: F625W (r)Red: F775W (i) + F814W (I) + F850LP (z) |
