VizieR Online Data Catalog: Line list for seven target PAndAS clusters (Sakari+, 2015)
Abstract
The targets were observed with the Hobby-Eberly Telescope (HET; Ramsey et al. 1998, Proc. SPIE, 3352, 34; Shetrone et al. 2007PASP..119..556S) at McDonald Observatory in Fort Davis, TX in 2011 and early 2012. The High Resolution Spectrograph (HRS; Tull 1998, Proc. SPIE, 3355, 387) was utilized with the 3-arcsec fibre and a slit width of 1 arcsec, yielding an instrumental spectral resolution of R=30000. With the 600 g/mm cross-disperser set to a central wavelength of 6302.9Å, wavelength coverages of ~5320-6290 and ~6360-7340Å were achieved in the blue and the red, respectively. The 3-arcsec fibre provided coverage of the clusters past their half-light radii; the additional sky fibres (located 10 arcsec from the central object fibre) provided simultaneous observations for sky subtraction. Exposure times were calculated to obtain a total signal-to-noise ratio (S/N)=80 (per resolution element), although not all targets received sufficient time to meet this goal.
