5. Use the spreadsheet or calculator to calculate the wavelength calibration coefficients. In the

spreadsheet program, find the functions to perform linear regressions.



If using Quattro Pro, look under

Tools | Advanced Math



If using Excel, look under

Analysis ToolPak

6. Select the true wavelength as the dependent variable (Y). Select the pixel number, pixel number

squared, and the pixel number cubed as the independent variables (X). After executing the
regression, you will obtain an output similar to the one shown below. Numbers of importance are
noted.
