Notes. The simulation was done for a single dust SED typical of the 10% faintest area of the sky, whose parameters are the median values found in the low NH i mask: Tobs = 20.8 K, βobs = 1.55 and τ353 = 9.6 × 10-7 (Table 3). The CIBA was modelled assuming partial correlation in frequency (see Appendix C for details). The noise and CIBA levels used for each resolution are given in Table C.1. The values given here are the standard deviations of the parameters Tobs and βobs obtained from three-parameter SED fits of 105 realizations; δnoise and δCIBA represent the separate contributions of noise and the CIBA to the total standard deviation.
