Knowledge of a star's projected equatorial rotational velocity, rotation period, and radius are used to select pole-on stars, which improve the chances of finding a planet with astrometric or direct-imaging techniques. A table of nearby solar-type stars seen nearly pole-on is presented. It is shown that this method is not suitable for discriminating equator-on systems and so cannot be used to select candidates for the photometric method of Borucki and Summers (1984). The main drawback of the photometric method is that planetary transits are rare events, so that an enormous observational effort is needed to get convincing detections.
