1995ApJS...97...89L IONIZED GAS IN THE HALOS OF EDGE-ON, STARBURST GALAXIES: DATA AND RESULTS MATTHEW D. LEHNERT AND TIMOTHY M. HECKMAN Received 1994 April 14, accepted 1994 August 8 ABSTRACT We present narrowband H{alpha} and broadband R images, as well as long-slit spectra oriented along the minor and major axes of a sample of about 50 edge-on (a/b => 2), infrared-warm (S_60 microns_/S_100 microns_ > 0.4), infrared-bright (S_60 microns_ >= 5.4 Jy) galaxies. The infrared luminosity of the sample ranges over 10^10^ - 10^12^ L_sun_. The spatially resolved spectroscopy includes the measurement of velocity relative to the nuclear velocity, full width at half-maximum, total integrated flux in the profile (for those spectra taken under photometric conditions) for the lines [N II] {lambda}{lambda}6548, 6583, [O I] {lambda}6300, H{alpha}, and [S II] {lambda}{lambda}6716, 6731 and line ratios as a function of slit position along both the major and minor axes. The resolution of the spectra are between about 3 and 5 A. The spectroscopic data are presented for 5 bins along each axis-a nuclear bin that is a sum of the CCD rows that cover the half-light diameter centered on the nucleus of the galaxy, two near-nuclear bins which are sums of the CCD rows that cover from one to two half-light radii on each side of the nucleus, and two off-nuclear bins which are sums of the rows at nuclear distances greater than two half-light radii on each side of the nucleus. Additionally, we present recession velocities, nuclear line asymmetries, rotation speeds, minor axis velocity shears, H{alpha} luminosities, R- band absolute magnitudes, minor axis H{alpha} "excess," and effective radii of the galaxies in H{alpha} and the R continuum. We defer discussion of the properties of the emission-line gas and their correlation with the infrared properties of this sample of galaxies to a later paper and limit ourselves to a presentation of the data and analysis.
