VizieR Online Data Catalog: 3D-HST Survey: grism spectra master catalog (Momcheva+, 2016)
Abstract
Most of the data described in this paper were obtained by the 3D-HST Treasury Survey (2010 October-2012 March), which was allocated 248 orbits of HST time during Cycles 18 and 19. These observations cover 124 pointings in four of the five deep fields observed by CANDELS (AEGIS, COSMOS, GOODS-S, and UDS; prog. ID 12177, 12328, 12177 and 11600) and constitute the largest effort to acquire space-based near-infrared spectra in these fields. A detailed description of the 3D-HST observations is presented in Brammer+ (2012ApJS..200...13B).
The fifth CANDELS field, GOODS-N, had already been observed with WFC3/G141, in a Cycle 17 program as part of AGHAST (A Grism Hα SpecTroscopic Survey; GO-11600, PI: Weiner), using a very similar observing strategy. ACS/G800L observations in GOODS-N were taken as part of GO-13420 in Cycle 21 (PI: Barro). We have included the ACS/G800L and WFC3/G141 GOODS-N data in our sample. In addition to the ACS/G800L and WFC3/G141 data, we also summarize the available archival WFC3/G102 observations for each field. See section 2 for further details. (2 data files).- Publication:
