Below is the resulting brightness profile, and a diagram showing the delta T (in seconds) between brightness peaks. The period between the major peaks is regular and near 1.20 seconds. This is similar to what I determined for this satellite in January 2009 (see my post here). There is a hint of 2 lesser peaks present between each main peak.
