摘要：

It is shown that previously derived periodogram "false alarm" significance levels underestimate possible statistical errors; this is due to the fact that the population variance of the data has been assumed known. It is suggested that the false alarm method should not be used to test for the presence of particular periodicities; instead, a well-known test due to R. A. Fisher is appropriate. A method of dealing with irregularly spaced data is also given.
