Possible sources of systematic error in solar Doppler rotational velocities are examined. Scattered light is shown to affect the Mount Wilson solar rotation results, but this effect is not enough to bring the spectroscopic results in coincidence with the sunspot rotation. Interference fringes at the

We publish here rotation results from Doppler velocity measurements made at Mount Wilson over a period of more than 14 years. Altogether data from 188 rotations are presented. These results are displayed in various tables and figures. Measurements of scattered light along with its effect on the meas

A new calibration of the spectrograph at the Mount Wilson 150-foot Tower Telescope demonstrates that all reported solar Doppler rates to date measured at 25250.2 with this instrument are too high by a factor of 0.55%.

A description is given of a newly-installed computer-operated image scanning and data system for the 150-foot Tower Telescope at the Mount Wilson Observatory. This new system provides improved flexibility, accuracy, and reliability in the magnetograph observations. ## I. Introduction Since 1957 t
