摘要：

We present Copernicus X-ray observations of Circinus X-1 made during August 1973 and April 1974. Our results confirm that the reported 12·3-day periodicity is spurious, and in addition, the data show a clear correlation between the low energy X-ray intensity and spectral slope. © 1975 Royal Astronomical Society.
