Inference of Alfvenic oscillations. Inferred plasma variables at the start of the C-2U shot #49040. Solid lines correspond with the expected values of the posterior distribution, and shaded areas are a measure of the uncertainty of the inferred variables corresponding to one standard deviation. a Separatrix radius Rs (blue) and o-point radius R0 times \(\sqrt 2\) (green). Rs is found to be proportional to the R0, in agreement with Eq. (7). b Trapped flux (blue) and the trapped flux approximation for a long FRC (green). c Separatrix length (distance between x-points). d Total plasma current. e o-point z position. f Vessel current imbalance
