Notes. Targets 2003 QR91, 2001 QC298, 1996 TS66 and 2002 GJ32 were not observed by Herschel. The latter two targets are from Brucker et al. (2009) and have been remodeled based on updated flux densities with significant changes in radiometric results. Flux densities of Teharonhiawako and 2001 QY297 have been updated from those in Vilenius et al. (2012), and they have been reanalysed in this work. PID is the Spitzer program identifier. Observing geometry (heliocentric distance r, Spitzer-target distance Δ and Sun-target-Spitzer phase angle α) is averaged over the individual observations. The “Dur.” column gives the total observing time of several visits. The durations of observing epochs were 48 days, except for 1998 SN165 and 2002 AW197, which had only one observation. The effective monochromatic wavelengths of the two MIPS bands we use are 23.68 μm and 71.42 μm. Targets below the horizontal line have i > 4.5°. In-band fluxes from Mueller et al. (in prep.). Flux densities presented in this table have been color-corrected.
