The purpose of this TC is to prepare a Technical Report to demonstrate the use of equivalence measures (especially the En-Score) for scalar and vectorial quantities in photometry.
For the vectorial quantities the focus is on chromaticity coordinates and spectral distributions. The comparison of luminous intensity distributions (LIDs) will be covered by suggesting distance measures without taking the measurement uncertainties and correlations into account.
