A possible good fit of our debris disc model to the photometric and interferometric constraints of Table 4 (). The model used here has a size distribution exponent of −5 with limiting grain sizes of a_min = 0.2 μm and a_max = 1000 μm, a surface density power law of −3, and it assumes a disc composed of 50% silicates and 50% carbonaceous grains. The dashed and dotted lines represent the total emission from the disc on a 6 AU field-of-view, respectively with and without the scattered emission. The photospheric SED, simulated by a NextGen model atmosphere, is represented by the two solid lines as seen pole-on (upper curve) and from the equatorial plane (lower curve). Only measurements plotted in red have been taken into account in the fit.
