dc.description.abstractRadial velocity measurements of spectrograms of μ¹ Bootis taken at the Dominion Astrophysical Observatory in Victoria show no evidence for variability in the radial velocity of the star, with either a short or a long period. This conclusion was reached after statistical tests for variability were performed on the data. A comparison of radial velocity measurements from normal contrast, Kodak IIa0, plates and high contrast, Kodak III0, plates reveals no detectable gain in accuracy from the use of high contrast. Measurements of radial velocities of μ¹ Bootis made with the oscilloscope machine are internally more consistent than those made with visual measuring machines. The mean radial velocity of μ¹ Bootis, taken over 83 measure­ments each of unit weight, is -13 .0 km/sec, with a standard error of about 2 km/sec. This large standard error is chiefly the result of errors in the effective wavelengths adopted for the star.en
