Notes. Targets 2002 TX300 (Lellouch et al. 2013)and 1999 KR16 (Santos-Sanz et al. 2012) have been reanalysed and their flux densities updated in this work. OBSIDs are observation identifiers in the Herschel Science Archive. The first OBSID of the consecutive OBSIDs/visit are given. Duration is the total duration of the two visits (70 and 100 μm filters were used for half of the duration each), mid-time is the mean UT time, r is the heliocentric distance at mid-time, Δ is the Herschel-target distance at mid-time, and α is the Sun-target-Herschel phase angle at mid-time (JPL Horizons Ephemeris System; Giorgini et al. 1996). Flux densities are colour-corrected and the 1σ uncertainties include the absolute calibration uncertainty of 5% in all bands. Targets above the horizontal line are confirmed Haumea family members while those below the line are probable dynamical interlopers. (a) Differential fluxes from visit 1 only. During visit 2 a background source was near the target location. This background source is close to the edge of the images from visit 1 and could not be properly compensated by the positive and negative images.
