Sabbatical-induced mass loss

During the academic year 2013/4, I have been on sabbatical at the Institute for Theory and Computation at the Harvard-Smithsonian Center for Astrophysics.  One of my projects is an investigation of mass loss by astronomers.  Based on data obtained over the last few years (see chart below), I find strong support for a sabbatical-induced effect, with an ingress timescale of ~6 months and depth of at least 33% or 0.44 mag.  (The single outlier from the trend is easily explained as a consequence of dinner at the DaDong Roasted Duck Restaurant in Beijing.)
