Abstract

We present H{alpha}-region integral-field spectroscopy for 137 low-inclination, intermediate to late-type galaxies. Spectroscopic data, obtained with SparsePak and the Bench Spectrograph on the WIYN 3.5m telescope, span 6475-6880 {AA} with an instrumental resolution of 13km/s ({sigma}). The spectral range includes H{alpha} and [NII]{lambda}{lambda}6548,6584 for every source, and in most cases includes [SII]{lambda}{lambda}6717,6731. We present and publicly release 18288 calibrated spectra and visually inspected Gaussian line fits to the H{alpha} emission. Most measurements yield a signal-to-noise ratio above 5 in integrated H{alpha} line flux, adequate to derive reliable line centroids and widths. Second kinematic components are required to adequately describe the emission-line profile in 15% of reliable data. The H{alpha} velocity dispersion distribution peaks at 18km/s, modestly increasing with H{alpha} surface brightness, reaching 20km/s at {Sigma}H{alpha}=10^40^erg/s/kpc^2^. Lower-flux secondary components, when present, have widths of ~50km/s. These results agree well with previous echelle measurements of nearby galaxies. Velocity-field analysis yields kinematic inclinations, with a sample mean of 26{deg}. Large kinematic asymmetries systematically affect kinematic inclination estimates in a small fraction of our sample. When deviations from circular motion are below 10% of the projected velocity, kinematic inclinations are consistent, within errors, to estimates from inverting the Tully-Fisher relation. This confirms previous disk-submaximality estimates for galaxies with regular kinematics based on inclinations derived from inverting the Tully-Fisher relation.
