DM-Ice17 is a NaI(Tl) experiment deployed directly below the IceCube Neutrino Observatory in the South Pole ice. It is comprised of two detectors, each containing a 5.5'' diameter, 6'' tall cylindrical scintillator. Muons are identified in DM-Ice17 by their event topology in the scintillator, and a high portion of tagged muons are coincident with events in IceCube. A study of these coincident events has shown that co-deployment of scintillators with Cherenkov detectors can improve low energy track reconstruction. Knowing that the direct path of the muon passes through the volume of the DM-Ice17 crystal lowers IceCube misreconstruction rates and provides a new metric for reconstruction quality. We present the status of the DM-Ice17/IceCube muon coincidence study and the status of the reconstruction improvements.
