I = fitsread('solarspectra.fts');%input your image
imshow(I,[]);

Create the intensity profile. Call improfile with no arguments. The cursor changes to cross-hairs when you move it over the displayed image. Using the mouse, specify line segments by clicking the endpoints. improfile draws a line between the endpoints. When you finish specifying the path, press Return. .
