  We present a combination of new and archival neutral hydrogen (HI)
observations and new ionized gas spectroscopic observations for sixteen
galaxies in the statistically representative EDGES kinematic sample. HI
rotation curves are derived from new and archival radio synthesis observations
from the Very Large Array (VLA) as well as processed data products from the
Westerbork Radio Synthesis Telescope (WSRT). The HI rotation curves are
supplemented with optical spectroscopic integral field unit (IFU) observations
using SparsePak on the WIYN 3.5 m telescope to constrain the central ionized
gas kinematics in twelve galaxies. The full rotation curves of each galaxy are
decomposed into baryonic and dark matter halo components using 3.6$\mu$m images
from the Spitzer Space Telescope for the stellar content, the neutral hydrogen
data for the atomic gas component, and, when available, CO data from the
literature for the molecular gas component. Differences in the inferred
distribution of mass are illustrated under fixed stellar mass-to-light ratio
(M/L) and maximum disc/bulge assumptions in the rotation curve decomposition.
