gaussian-fit

In Physics it is common to fit spectral peaks and dips with gaussian curves in order to estimate their position and broadening. I did this task by taking the logarithm of the data and providing a second order polynomial fit on it.

Gold nanostructured surfaces exhibit resonance phenomena between localized plasmonic waves and incoming light at visible spectral range. Angle resolved reflectance measurements provide peaks at wavelengths that depends on the angle of reflectance. A gaussian fit is necessary in order to properly find the dip position at each angle

Just to remember how to get a time variating plot on IPython 2.7. The graph is the squared Fourier Transform of the step function, a typical application of which is light diffraction pattern from a squared hole
