Log of the 1996 observation: ObsId 2025800800.

Orbit	T start	Exposure	Rate (ct/s)
	(s)	(s)	MECS^*	PDS^*

1	0	500	273.5 ± 11	31.1 ± 2
2	2910	2080	276.1 ± 10	33.2 ± 3
3	8688	2473	267.6 ± 10	33.4 ± 3
4	14 458	2919	299.1 ± 11	35.2 ± 4
5	20 119	2912	267.8 ± 12	33.8 ± 4

Notes. The columns list the sequential number of the orbits, the time in seconds from the starting time (1996 November 15 20:30:12 UTC), the exposure time and the rate detected in three MECS units.

^(*)

Errors are computed in light curves with 10 s integration time bins with the rms with respect to the average along the orbit, to be compared with the average Poisson error that is 5 ct/s for the MECS and 2 ct/s for the PDS.
