GeMS/GSAOI Observations of a Frontier Field
February 13, 2014
The cluster MACSJ 0416.1-2403, one of the Hubble Space Telescope Frontier Fields, has been observed using GeMS/GSAOI. The raw data are now publicly available, and reduced data products will be provided later.
Deep images for a total of 5.3 hours of on-source integration time were obtained in January 2014 using the Kshort filter. During the observations, the AO-corrected FWHM varied from 0.075 arcsec to 0.100 arcsec. The GeMS/GSAOI pointing observations are offset from the cluster center to accommodate the required guide stars, centered on the coordinates RA=04:16:07.981, DEC=-24:04:50.18.
The public data, from program GS-2013B-DD-1, can now be obtained from the Gemini Science Archive, with raw data here. Instructions for obtaining calibrations are at the Gemini website. The GSAOI package within the Gemini IRAF package provides tools for basic data reduction, excluding mosaicking.
