Walkthrough# This page contains a series of Jupyter notebooks to show the main features of optifik. Choice of method Introduction Step 1: Loading Experimental Data from a .xy File Step 2: Data Smoothing Step 3 : Find peaks Generalities on the library Thick films : Fast Fourier Transform (FFT) Method Intermediate thickness: Peak fitting Scenario 1: Successful peak fitting Scenario 2: Small errors detection Small thickness : Scheludko renormalisation Case 1 : Non-zero interference order \(m\) Case 2 : zero interference order \(m\)
