VizieR Online Data Catalog: IRTF J-band spectrum of Mrk 231 (Leighly+, 2014)
Abstract
Mrk 231 was observed using SpeX (Rayner et al. 2003PASP..115..362R) on the NASA Infrared Telescope Facility (IRTF) on 2010 April 24 for 30 minutes. A standard ABBA integration scheme was used. The A0 star HD 112623 was used for flux and telluric corrections. The spectra were reduced, and the telluric correction applied, in the standard manner using Spextool and accompanying software (Cushing et al. 2004PASP..116..362C; Vacca et al. 2003PASP..115..389V). The resolution measured from the arc lamp lines was about 12 Å FWHM, or 330 km/s in the vicinity of the absorption line. The galactic reddening in the direction of Mrk 231 is E(B-V)=0.0095, and we corrected for that using the CCM reddening curve (Cardelli et al. 1988ApJ...329L..33C).
