Observational photometry and model fits of IRAS 17392−3020. For each photometric observation, the uncorrected flux density (lower red symbols) and the de-reddened flux density for A_Ks = 1.8 mag (upper blue symbols) are given. The best-fitting models are given as dotted (red) curve for the observed photometry and as solid (blue) curve for the de-reddened photometry. The de-reddened bolometric flux is a factor 2.2 enhanced. Symbols are as in Fig. A.1.
