Figure 4: Spectrum of the SAX J1747.0-2853 obtained during the observation on 2000 April 7, when the source was in the minimum between the two peaks. The spectrum is fitted with Comptonization, disk blackbody and a narrow line, all with absorption. The equivalent width of the iron line at this observation is the highest of all observations. |

Figure 6: The PCA lightcurve of SAX J1747.0-2853 with the times (as indicated by horizontal lines) when the BeppoSAX WFC had the source in its field of view with sufficient sensitivity, and with the times of the detected X-ray bursts (as indicated by vertical dotted lines; this includes the four NFI and ASCA detected bursts). The number of the detected X-ray bursts in an observation window is indicated over the horizontal lines. |
