We present timing and spectral analysis of Rossi X‐ray Timing Explorer‐Proportional Counter Array observations of SMC X‐1 between 1996 January and 2003 December. From observations around 1996 August 30 with a time‐span of ∼6 d, we obtain a precise timing solution for the source and resolve the eccentricity as 0.00089(6). We find an orbital decay rate of which is close to the previous results. Using...
