SED of RZ Psc. A K0 IV model photosphere (Pickles 1998) fits the optical and near-IR measurements shortward of 3 μm. Longward of 3 μm, the excess emission is markedly dominant and contributes 8% to the total source luminosity. The solid black line corresponds to the total flux of the stellar photosphere plus a single black-body curve of 500 K. Some uncertainties in the flux measurements are smaller than the plot-symbol. The errorbars in wavelength indicate the width of the filter, which corresponds to 50% of the transmission.
