Beginning of ReadMe : J/ApJ/663/218 Optical Spectroscopy of WIYN Hydra FLS sources (Marleau+, 2007) ================================================================================ Spectroscopic survey of 1.4GHz and 24mum sources in the Spitzer First Look Survey with WIYN Hydra. Marleau F.R., Fadda D., Appleton P.N., Noriega-crespo A., Im M., Clancy D. <Astrophys. J., 663, 218-233 (2007)> =2007ApJ...663..218M ================================================================================ ADC_Keywords: Galaxies, IR ; Radio sources ; Redshifts ; Spectroscopy Keywords: galaxies: bulges - galaxies: evolution - galaxies: high-redshift - galaxies: spiral - galaxies: starburst - infrared: galaxies Abstract: We present an optical spectroscopic survey of 24um and 1.4GHz sources, detected in the Spitzer extragalactic First Look Survey (FLS), using the multifiber spectrograph, Hydra, on the WIYN telescope. We have obtained spectra for 772 sources, with flux densities above 0.15mJy in the infrared and 0.09mJy in the radio. The redshifts measured in this survey are mostly in the range 0<z<0.4, with a distribution peaking at z 0.2. Description: Our WIYN Hydra target sample was selected from two data sets of sources detected in the FLS. The first set was comprised of sources detected at 1.4GHz and with an R-band magnitude <23. This set was used during our 2002 and 2003 observing runs, prior to the Spitzer launch (2003 August 25). The second set was constructed from the 24um sources, using the same R-band magnitude cut. These were targeted during our 2005 observing run after the Spitzer observations of the FLS were completed (2003 December 9-11). A few companions of 1.4GHz and 24um sources were also part of the sample.
