  We report the timing and spatial resolution from the Muon Telescope Detector
(MTD) installed in the STAR experiment at RHIC. Cosmic ray muons traversing the
STAR detector have an average transverse momentum of 6 GeV/c. Due to their very
small multiple scattering, these cosmic muons provide an ideal tool to
calibrate the detectors and measure their timing and spatial resolution. The
values obtained were ~100 ps and ~1-2 cm, respectively. These values are
comparable to those obtained from cosmic-ray bench tests and test beams.
