Table 1

Basic parameters of the H2 column density maps of the four Berschel fields displayed in Fig. 1.

G210 l = 210.90°
b = −36.55°
d = 140 ± 20pc
1px = 12″ → 0.0081 pc
Δl × Δb = 1.28° × 1.22° → 3.1 pc × 3.0 pc
ϵ [0.2, 7.5] × 1021 cm−2
G300 l = 300.86°
b = −9.00°
d = 150 ± 30pc
1px = 12″ → 0.0087 pc
Δl × Δb = 0.64° × 0.68° → 1.7 pc × 1.8 pc
ϵ [0.6, 8.2] × 1021 cm−2
G82 l = 82.65°
b = −2.00°
pc
1px = 12″ → 0.036 pc
Δl × Δb = 1.37° × 1.41° → 14.9 pc × 15.3 pc
ϵ [2.7, 42] × 1021 cm−2
G202 l = 202.02°
b = +2.85°
d = 760 ± 100 pc
1px = 12″ → 0.044 pc
Δl × Δb = 1.22° × 1.17° → 16.2 pc × 15.6 pc
ϵ [0.6, 58] × 1021 cm−2

Notes. Parameters are ordered by increasing distance: Galactic longitude, l, Galactic latitude, b, distance d (taken from Saajasto et al. 2017 for G82 and Montillaud et al. 2015 for the other fields), angular and physical sizes of a pixel (equal to one-third of the beam size), angular and physical dimensions of the map, Δl × Δb, and range of the H2 column density, .
