The preparation of tables of coefficients of utilisation from the Jones-Neidhart data is a much more lengthy process than from the Harrison-Anderson data. The method given in this paper is based on the Jones-Neidhart data, but the work involved in applying it is about the same as that for the Harrison-Anderson method. It also provides sufficient information for brightness calculations to be carried out.
