Table 1
List of parameters of selected NLFF dips.
| Dip | Parameters |
|
|
|
| Deep_dip | T0 = 8000 K; M0 = 2 × 10-4 g cm-2 |
| ptr = 0.015 dyn cm-2; pcen = 0.13 dyn cm-2 | |
| Ttr = 105 K; γal = 2; γac = 60 | |
|
|
|
| Shallow_dip | T0 = 8000 K; M0 = 0.5 × 10-4 g cm-2 |
| ptr = 0.03 dyn cm-2; pcen = 0.035 dyn cm-2 | |
| Ttr = 105 K; γal = 2; γac = 60 | |
Notes. T0 represents the central minimum temperature; Ttr is the transition-region temperature at the edge of a dip; M0 gives the maximum column density in the middle of the thread; ptr represents the boundary gas pressure; and pcen is the central gas pressure derived from the hydro-static equilibrium; exponent γal describes the temperature gradient along the field; exponent γac describes the steep temperature gradient across the field.
