| About the Data |
| Data Description: |
The Hubble image was created from HST data from proposal 10246: M. Robberto (STScI/ESA), C.R. O'Dell (Vanderbilt University), L.A. Hillenbrand (Caltech), M. Simon (SUNY Stony Brook), P. McCullough (STScI), J. Krist (Jet Propulsion Laboratory), F. Palla (Osservatorio Astrofisico di Arcetri), M. Romaniello (ESO – Germany), J. Najita (NOAO/AURA), E.D. Feigelson (The Pennsylvania State University), R. Makidon (STScI), J. Stauffer (Jet Propulsion Laboratory); N. Panagia, I.N. Reid, D.R. Soderblom, and E. Bergeron (STScI); and K.G. Stassun (Vanderbilt University).
The Hubble data was superimposed onto a ground-based image taken from the 2.2 meter telescope at the European Southern Observatory – La Silla. |

| Color: |
This image is a composite mosaic of many separate expposures made by the ACS instrument on the Hubble Space Telescope and the ESO La Silla 2.2 meter telescope using several different filters isolating the light of specific elements or of specific broad wavelength ranges. The color arises by assigning different hues (colors), to each monochromatic image. In this case, the colors are:
HST:
F658N Ha red/orange
F850LP z red
F775W i red
F555W V green
F435W B blue |
ESO MPI 2.2m La Silla WFI Dec. 11, 2001:
NB#Halpha/7_ESO856 Ha red
NB#SIIr/8_ESO857 [S II] red
NB#OIII/8_ESO859 [O III] green
BB#B/99_ESO842 B blue |
