Here is an example of a single surface bump fit with a quadratic model. The green line is the initial guess (before fitting), the red line is the final model (after fitting), and the -blue dots are measured data points. +blue dots are measured data points. The red dots in the bottom panel +are the residual, which looks cubic because we've subtracted a +quadratic model.
