Caption: Figure 2.
A demonstration of the line-fitting routines used on the Hα profile taken from a pixel within a fibril. In the upper panel, the pluses show the IBIS data, the dashed blue line shows a Gaussian profile fit described by Equation (1), and the solid blue line shows a super-sech profile fit described by Equation (2). The lower panel shows the residuals of these two fits with the same colors.
