2. Data

We have analysed four RXTE/PCA observations of XTE J1858+034 made in the high state of the source. The raw data was obtained from the XTE Science Operations Facility (SOF) public data archive. We generated light curves from the raw data in two energy bands 1.3-7 keV and 7 keV with 1 s time resolution. Details of the data used for this analysis, with start and end time of the data stretches, average PCA background subtracted count rates etc. are given in Table 1. The light curves obtained from these observations are shown in Fig. 1 with 5 s time bin. Information about the PCA detectors and the RXTE can be found in Jahoda et al. (1996).

Table 1. The observation log

Fig. 1. The background subtracted X-ray light curves of XTE J1858+034 obtained from PCA detectors in the energy range of 1.3-100 keV are shown for the four observations (described in the text). The time bin is 5 s. Modulations at the 221 s pulse period are clearly seen.
