Notes. The data were taken with the mini-scan map mode at a scan speed of 20′′/s and scan angles, with respect to the instrument, of 70° and 110°, in the blue (70 μm) and red (160 μm) bands simultaneously. Note, that phase angles α are positive before, and negative after opposition. λc is the central reference wavelength and FD is the monochromatic and colour-corrected flux density at λc.
