Integral Field Near-Infrared Spectroscopy of a Sample of Seyfert and LINER Galaxies. I. The Data

We present near-IR integral field spectroscopy of a sample of 31 Seyfert and LINER galaxies which were selected both to span a wide range of nuclear magnitudes and to possess roughly equal numbers of Seyfert type 1 and 2 nuclei. Moderate resolution (R ~ 1000; R ~ 2000 for three cases) integral field K-band spectra were obtained for all 31 galaxies in our sample and for 18 galaxies (R ~ 1000; R ~ 2000 for four cases) H-band integral field spectra were also obtained. In each case, we present nuclear, larger aperture, and difference spectra with corresponding information about emission line wavelengths, fluxes, and widths. Line-free H- and K-band continuum images as well as [Fe II] λ1.644 μm, Brγ, and H2 1-0 S(1) emission lines are also presented. In addition, we provide extensive information about each galaxy obtained from the literature that will be useful subsequently for characterizing the sample and for comparison with our near-IR data.
