Notes.

^(a)

Mean over the whole sky of the integration time cumulated for all detectors (definition as in Table 3) in a given frequency channel.

^(b)

Fraction of the sky whose coverage is less than half the Mean.

^(c)

Fraction of the sky whose coverage is larger than four times the Mean.

^(d)

Fraction of the sky whose coverage is larger than nine times the Mean.
