Energy calibration of the PILATUS detector for a single-pixel cell at 299 K operation temperature: (a) the calibration curve (energy versus frame number) obtained after fitting Fe, Cu, Br, Y, Mo and Ag spectra [see Fig. 1(b)] with its further approximation by a third-order polynomial function; (b) verification of fitting curves and their difference showing the calibration drift following a ROC temperature change from 299 to 297 K. |
