MACS0717.5+3745 Complete


As of 2014 February 19 the GLASS observation of MACS0717 are complete. Hence, the full GLASS data set on the first of the 10 targeted clusters is available and ready for exploration.

The dataset includes 4 orbits of HST WFC3 G141 grism spectroscopy, 10 orbits of HST WFC3 G102 grism spectroscopy, and 2×7 orbits of HST ACS G800L grism spectroscopy. The WFC3 data are all on the core of the cluster taken at two different position angles to minimize the effect of contamination. The ACS spectroscopy are on the two parallel fields.
