Notes.

(a)

Total number of channels in the selected frequency range.

(b)

Number of selected channels, excluding the blanked channels, and those in the absorption parts of the spectrum when explicitely mentioned.

(c)

Number of channels above the detection threshold (90 mK in main-beam temperature scale).

(d)

Number of identified channels, i.e. channels for which the temperature of the synthetic spectrum reaches at least 50% of the observed temperature.

(e)

Estimated number of lines detected in emission.

(f)

Integrated intensity of the absolute value of the observed spectrum over the range of detected channels.

(g)

Integrated intensity of the synthetic spectrum over the range of detected channels.

(h)

Difference between Cols. 7 and 8 (Iobs − Imod).

(i)

Integrated intensity of the difference between the absolute value of the observed spectrum and the absolute value of the clipped synthetic spectrum over the range of detected channels. The synthetic spectrum is clipped to the observed spectrum in the channels for which the synthetic temperature is higher than the observed temperature in absolute value.

(j)

Fraction of selected channels (Nsel/Ntot).

(k)

Fraction of detected channels (Ndet/Nsel).

(l)

Fraction of recovered integrated intensity (1 − IdiffPos/Iobs).

(m)

Average fraction of recovered temperature per channel, after clipping the synthetic spectrum like in Col. 10.

(n)

Fraction of identified channels (Nid/Ndet).
