Notes. (i)The primary parameters are noted in bold, while the numbers in light are derived from these primary numbers. For the experimental streams, the primary numbers are directly measured or are deduced from simulations, as detailed in the text. For the EXor object, the B-field value is an assumed one denoted with • symbol, and the parameters reported by Giannini et al. (2017) are denoted with ⋆ symbol.
