Notes.In Method C the column density estimate is p1 × N(500) + p2 × [N(350) − N(350 → 500)] + p3 × [N(250) − N(250 → 350)], in Method D the estimate is p1 × N(250 → 500) + p2 × N(350 → 500) + p3 × N(500). The second column specifies the selection of the analysed region, based on column density or the area around the selected cores.
