High-quality stellar spectra are in great demand now - they are the most\nimportant ingredient in the stellar population synthesis to study galaxies and\nstar clusters. Here we describe the procedures to increase the quality of flux\ncalibration of stellar spectra. We use examples of NIR intermediate-resolution\nEchelle spectra collected with the Folded InfraRed Echellete (R~6500, Magellan\nBaade) and high-resolution UV-optical spectra observed with UVES (R~80000, ESO\nVLT). By using these procedures, we achieved the quality of the global\nspectrophotometric calibration as good as 1-2%, which fulfills the requirements\nfor the quality of stellar spectra intended to be used in the stellar\npopulation synthesis\n
