Description

An analysis is reported of the average pulse shape of Cen X-3 versus energy (2--20 keV) on time scales of hours to days derived from Uhuru observations during 1971 May 5--7 and 1971 December 18--20. The pulsed fraction varied with energy from 0.42 +- 0.02 to 0.80 +- 0.10 over the 2--20 keV range. The 2--6 keV pulsed fraction did not show statistically significant variations (>2 sigma) over the phase of the 2.087 day eclipse cycle. Individual measurements of the 2--6 keV pulsed fraction ranged from 0.45--0.56
