The ISOPHOT data presented in this paper were reduced using PIA, which is a joint development by the ESA Astrophysics Division and the ISOPHOT Consortium with the collaboration of the Infrared Processing and Analysis Center (IPAC). Contributing ISOPHOT Consortium institutes are DIAS, RAL, AIP, MPIK, and MPIA.

... extraction

Even bright sources like Ceres are sometimes difficult to analyse if they are in regions of high background like at $\lambda_{{\rm ecl.}}=90^{\circ}$ and $\lambda_{{\rm ecl.}}=270^{\circ}$ , where the ecliptic crosses the galactic plane.

... correction

There seems to be a wrong application (multiplication instead of division) of the colour correction factor by Grün et al. (2001). For consistency, we do however apply all corrections as given in their paper.
