Measurements of absolute differential muon intensities have been made with the Texas A M--University of Houston solid-iron magnetic spectrometer at axis orientations of 0/sup 0/, 65/sup 0/, and 80/sup 0/. The momentum range covered is from 2 to 300 GeV/c although emphasis has been on the accuracy of measurements from 20 to 50 GeV/c. The large-zenith-angle orientations have allowed measurements of the intensity over the zenithal range 55/sup 0/--85/sup 0/. The actual measured intensities are presented along with the final corrected intensities evaluated at standard momenta. These measurements, made with a single instrument, may serve as normalization intensities for large-zenith-angle high-MDM (maximum detectable momentum) spectrometers which cannot be operated at arbitrary axis orientations and for which intensity-normalization points at moderate energies can be useful. The results are shown to be consistent with the most recent measurements from the Kiel-DESY magnetic spectrometer. The procedures for recording and analyzing the data are presented in detail.
