should be noted that the obtained estimates really are upper bounds rather than two-sided limits. It is because we exclude the components, which then are used in some linear combination and thus are additionally normalized. It may, in general, reduce the effect of spectrum censoring.

COBE data analysis shows (see Table \[tbl\_n\]) that the procedure of the anomalous harmonics excluding effects the significant change in $n$. If the instrumental noise is completely random the probability to obtain so large difference is smaller than $0.02\%$. One may see that the applying the anomalous harmonics censoring to COBE data causes a dramatically decreasing of the strange dependence of the results on whether or not the quadrupole is excluded. It may be an indirect support to the necessity of proposed data censoring.

Basing on the obtained parameters we may predict the signal in an experiment like it is conducted in Tenerife (Hancock et al., 1994). Assuming $5.5^{\circ}$ beam, $8.1^{\circ}$ antennae separation, and 3-point method of observation i.e. $\Delta T = T_0
-0.5(T_1 + T_2)$, we may calculate the following data for the spectrum (\[approx\_DTT\]) type using previously obtained $Q_2$ and $n$, excluding components with anomalous noise and applying the spatial filtering: $\sigma_{Tenerif} =
