VizieR Online Data Catalog: Spectroscopy of the fields of gravitational lenses (Wilson+, 2017)

The lens sample selection is described in Momcheva+ (2015, J/ApJS/219/29).

For 26 of the 28 fields with the most complete spectroscopic data, Wilson+ (2016, J/ApJ/833/194) created a group catalog including any groups projected along the sightline to the lens as well as groups in which the lens galaxy is itself a member. The properties of these 26 fields are listed in Table 1.

The Mosaic-1 imager on the Kitt Peak National Observatory Mayall 4m telescope and the Mosaic II imager on the Cerro Tololo Inter-American Observatory Blanco 4m telescope were used to collect images through the "nearly Mould" I-band filter and either the Harris V filter or the Harris R filter (depending on the redshift of the lens galaxy).

The spectra were obtained using Hectospec on the MMT 6.5m telescope and LDSS-2, LDSS-3, and IMACS on the Magellan 6.5m telescopes.
