Inference of plasma magnetic related variables. Solid lines correspond with mean values of the posterior distribution, and shaded areas are a measure of the uncertainty of the inferred variables corresponding to one standard deviation for shot # 48269. a Separatrix radius Rs (blue) and o-point radius R0 times \(\sqrt 2\) (green). b Trapped flux (blue) and the trapped flux approximation for a long FRC (green). c Machine axis Bz at the o-point z position (blue) and comparison with the long FRC approximation (green). d Separatrix length (blue) compared with the approximation from excluded flux (green). e Total plasma current (blue) and comparison with the long FRC approximation (green). f Total vessel current
