Examples of workflow components. Illustrations are given for artifact correction and axis calibration. Characteristic 1D distributions of the measured X, Y, TOF, ENC and an arbitrary axis are shown on the very left. U(0,1) represent uniformly distributed random noise added to suppress digitization artifacts (jittering or dithering). The transforms (g’s) are calibration functions that convert the values in the measurement axes to the physical ones. The transform \({\mathcal{L}}\) (X,Y) corrects the symmetry distortion, while the spherical timing aberration and space charge are compensated for by ΔTOFsph and ΔTOFsc, respectively. Binning of the corrected single-event data over the calibrated physical axes yields a multidimensional hypervolume (right picture) of photoemission intensity data along with the physical axes values.
