摘要：

We present the results of a systematic search in 8.5 yr of Rossi X-Ray Timing Explorer All-Sky Monitor data for evidence of periodicities. The search was conducted by application of the Lomb-Scargle periodogram to the light curves of each of 458 actually or potentially detected sources in each of four energy bands ( 1.5 - 3, 3 - 5, 5 - 12, and 1.5 - 12 keV). A whitening technique was applied to the periodograms before evaluation of the statistical significance of the powers. We discuss individual detections with a focus on relatively new findings.
