Making sense of sunspot decay - II. Deviations from the Mean Law and Plage Effects
In a statistical analysis of Debrecen Photoheliographic Results sunspot area data we find that the logarithmic deviation (logD)' of the area decay rate D from the parabolic mean decay law (derived in the first paper in this series) follows a Gaussian probability distribution. As a consequence, the actual decay rate D and the time-averaged decay
