Physical properties of the globule in total (Col. 2) and the head and tail (Cols. 3 and 4), respectively.

|---|---|---|---|
| ⟨N⟩ [1021 cm−2] | 14.2 | 14.3 | 14.0 |
| Mass [M⊙] | 238 | 166 | 73 |

 [K] |
19.7 | 19.7 | 17.0 |
| Length [pc] | 1.78 | 0.85 | 0.93 |
| Width [pc] | 0.3–0.9 | 0.9 | 0.3 |
| Area [pc2] | 0.9 | 0.62 | 0.28 |
| Average UV-field [G°] | 550 | 170 | |
| Peak UV-field [G°] | 4300 | 220 | |
| Incident UV-field [G°] | 150–600 | 150–600 | 150–600 |
Notes. The values were derived from the Herschel column density and temperature maps (Schneider et al. 2016). A distance of 1.4 kpc was assumed, so that 1′ corresponds to 0.4 pc. The area is the equivalent area of a polygon used to derive the mass, density etc. ⟨N⟩ is the average H2 column density. The average and peak flux values were derived from the Herschel fluxes, explained in Schneider et al. (2016), the incident UV-flux from a census of the stars from Cyg OB2.
