WAXS-calibration


This Javascript does the calibration of a 1D-WAXS-curve in transmission mode with a Calibration sample (preset here: PBBA ( p-bromobenzoic acid), CSD Entry: BRBZAP01). Enter d-spacings of the diffraction peaks and the respective the pixel or peak position values of the 1D-detector for the max. 6 calibration peak positions. If a peak or more is/are not visible or cannot be detected enter -1. The resulting equation for the q-scale is then: q = intercept + slope*pixel. Note: the linear relationship between q and pixel position is only valid over a small angular range by using a plane position sensitive 1D detector. Unit of q is 1/A if the values of the peak positions or spacing is also in A. The values of the slope and of the intercept will be displayed and the fit will be plotted.
