1D profile of the [S ii]31/16 ratio along the flow, derived from integration of the line surface brightness across the jet and over each velocity interval. Horizontal dashed lines indicate upper and lower density limits on validity of the ratio as a ne diagnostic. Empty symbols mark positions and velocities for which the modified BE-technique has been applied. Upper and lower limits arise when one of the lines is undetected, and so its flux has been set to 3σ.

Same as Fig. 16 for the logarithm of the [N ii]/[O i] line ratio.

thumbnail Fig. 18

Same as Fig. 16 for the [O i]/[S ii] line ratio. Due to the prominence of [O i] emission over the [S ii] lines close to the star, a few points are off the scale. Their values are: 6.58 at 0.̋175, for the MVI, and 12.10, 14.49, 9.54 and 4.99 at 0.̋175, 0.̋275, 0.̋375 and 0.̋475, respectively, for the HVI.
