Verifies that the integral of pseudo-Gaussians (such as used in thermogravimetry) is an ERF function.

Draws plots of: the experimental (given data) curve; and the adjusted curve.

The number of components (in the base case, 4) is, of course, 1⁄3 the number of parameters, as the pseudo-Gaussians are of the form  a exp{−[(T−b)⁄c]²}.
