Notes. The fractional errors are derived assuming a binomial distribution (see text).

(a)

Region numbers as in Fig. 1; each region is 0.5 deg on a side.

(b)

Lowest and highest log N(H) values included in the fit to the power-law index of the PDF.

(c)

PDF power-law index errors are estimated using the Δ χ2 = 1.0 interval.

(d)

Fraction of Class 0 protostars relative to the total number YSOs: NClass0/NYSO.

(e)

Integrated properties of the above regions.
