Beginning of ReadMe : J/ApJ/750/168 Redshift survey in the Subaru GTO2deg^2^ field (Kurtz+, 2012) ================================================================================ Testing weak-lensing maps with redshift surveys: a Subaru field. Kurtz M.J., Geller M.J., Utsumi Y., Miyazaki S., Dell'Antonio I.P., Fabricant D.G. <Astrophys. J., 750, 168 (2012)> =2012ApJ...750..168K ================================================================================ ADC_Keywords: Redshifts ; Spectroscopy ; Photometry, SDSS ; Galaxies, optical ; Surveys ; Gravitational lensing ; Clusters, galaxy Keywords: cosmology: observations - galaxies: clusters: general - galaxies: distances and redshifts - gravitational lensing: weak - large-scale structure of Universe Abstract: We use a dense redshift survey in the foreground of the Subaru GTO2deg^2^ weak-lensing field (centered at 16:04:44+43:11'24 (2000) to assess the completeness and comment on the purity of massive halo identification in the weak-lensing map. The redshift survey (published here) includes 4541 galaxies; 4405 are new redshifts measured with the Hectospec on the MMT. Among the weak-lensing peaks with a signal to noise greater than 4.25, 2/3 correspond to individual massive systems; this result is essentially identical to the Geller et al. (2010ApJ...709..832G) test of the Deep Lens Survey (DLS) field F2. The Subaru map, based on images in substantially better seeing than the DLS, enables detection of less massive halos at fixed redshift as expected. We demonstrate that the procedure adopted by Miyazaki et al. (2002ApJ...580L..97M) for removing some contaminated peaks from the weak-lensing map improves agreement between the lensing map and the redshift survey in the identification of candidate massive systems. Description: Miyazaki et al. (2002ApJ...580L..97M, 2007, Cat. J/ApJ/669/714) used the 8.2m Subaru Telescope to carry out a weak-lensing survey of 13 well-separated fields covering a total of 21.82deg^2^. They used lensing convergence maps to identify 100 candidate halos with S/N nu>3.7; 10 of these candidates are within the GTO2deg^2^ field we examined here. We constructed the galaxy catalog from the Sloan Digital Sky Survey (SDSS; Adelman-McCarthy et al. 2008, Cat. II/294) r-band galaxy list for the GTO2deg^2^ field. We acquired spectra for the objects with the Hectospec, a 300-fiber robotic instrument mounted on the MMT from 2009 February 1 to 2009 April 27. The spectra cover the wavelength range 3500-10000AA with a resolution of 6AA.
