Cen X-3 has a period near the the Nyquist limit of 2.048s for the DISCLA data used by the Monitor, so that these measurements lose some power due to aliasing. The flux has been corrected by a factor of 1.08 to obtain the values plotted above. Data have been averaged over 2 days. Eclipses are not accounted for in the above flux measurement, so flux values are too low by the ratio of the eclipse duration to the orbital period.
