DECH software provides all stages of CCD echelle-image-spectra processing: bias/background subtraction, flatfield division, one--dimensional spectrum extraction from 2-dimensional images, correction for diffuse light, spectrum addition and exclusion of cosmic ray features. One can also set a continuum, and measure equivalent widths, line positions and displacements.
