Notes. All data were taken in ‘mini-scan map’ observing mode, using high gain and satellite scan speed of 20″ s−1. The columns are: OD, operational day; OBSID, Herschel observation ID of the measurement; SAA, solar aspect angle; Dur., duration of observation in minutes; Band, filter–band combination; Rep., repetition of entire scan map; rh, heliocentric distance; ∆, observer distance; α, phase angle; 
and 
, mean in-band flux density in the 100 and 160 µm bands of the measurement block. All measurements were performed with 3.0′ scan-leg length, ten scan legs, 4.0″ scan-leg separation, and 110° satellite scan angle with respect to instrument reference frame.
