About the Data

Data Description:	The Hubble images were created from data from the calibration proposal 11452: E. Sabbi, J. Kim Quijano, and L. Dressel (STScI). The proper motions of stars in the cluster were obtained from the following ACS proposals: 9442 A. Cool (San Francisco State Univ.), J. Anderson (STScI), C. Bailyn (Yale Univ.), J. Carlin (San Francisco Univ.), P. Edmonds (Eureka Scientific), J. Grindlay (Harvard Univ.), and D. Haggard (Univ. of Washington); 10252: J. Anderson (STScI) and I. King (Univ. of Washington); and 10775: A. Sarajedini (Univ. of Florida), J. Anderson (STScI), A. Aparicio (Inst. de Astrofisica de Canarias), L. Bedin (STScI), B. Chaboyer (Dartmouth College), I. King (Univ. of Washington), S. Majewski (Univ. of Virginia), G. Piotto (Univ. of Padua), N. Reid (STScI), A. Rosenberg (Inst. de Astrofisica de Canarias), and M. Siegel (Univ. of Texas, Austin)
Instrument:	ACS WFC3/UVIS
Exposure Date(s):	ACS: June 27-30, 2002, December 11, 2004, and June 22, 2006 WFC3/UVIS: July 15, 2009
Exposure Time:	2.7 hours
Filters:	F225W (U), F275W (U), F336W (U), F438W (B), F606W (V), and F814W (I)

Color:

The image is a composite of separate exposures made by the WFC3 instrument on the Hubble Space Telescope. Three filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:

F814W (I)	red
F336W (U)	green
F225W (U)	blue
