Figure 3.

Flux density distribution of RZ Psc, including 2MASS, WISE, AKARI, VISIR and IRAS data and their (approximate) year of observation. The dark blue line shows a stellar photosphere model at the approximate stellar temperature of 5350 K, and the light blue line a 500 K blackbody. The latter is not a fit, but an approximate continuum level that illustrates that the WISE 3.4 and 22 μm photometry cannot both be accounted for with a single blackbody, if the silicate feature seen with VISIR was present in 2010.
