although a tension-driven flow is embedded within the structure of the [[helical jet]{}]{}(PAD09). In Sect. \[sec:Betadriver\], we further study the physics and properties of the wave beyond that of our previous analysis.

In PDD15 we presented two parametric studies of the generation of [[straight jets]{}]{}and [[helical jets]{}]{}: one varied the inclination angle of the coronal magnetic field while the other varied the photospheric distribution of the magnetic field while preserving the basic topology. We confirmed that the basic model of PAD09 was valid across a broad parametric range. PDD15 showed that [[helical jets]{}]{}are triggered for inclination angles in the range $\theta = 0 - 20^\circ$. As long as a 3D magnetic null point is present, our model is also valid for different photospheric distributions of flux concentrations surrounding the central embedded-bipole polarity, configurations that are frequently observed in the solar atmosphere.

We showed in PDD15 that a [[helical jet]{}]{}was generated for all inclinations but this is not true for the [[straight jet]{}]{}. A [[straight jet]{}]{}formed only when the 3D null point was sufficiently stressed to form an extended current sheet in response to the boundary-driven motions. We found that [[straight jets]{}]{}appear only for inclination angles $\gtrsim 8^\circ$. We also found
