Notes. The recovery rate corresponds to the fraction of lines of sight where measurement of the B-field orientation from polarized dust emission recovers the integrated B-field orientation within an error of <15° in the modeled Class 0 envelopes. The percentages shown in this table correspond to the averaged recovery rate, while the standard deviation of each measurement is given in a smaller font next to each mean value. The results are separated in two cases: moderate magnetic field (μ = 3.33, simulations R1, R2, R6, R7, and R10) and weak magnetic field (μ = 6.67, 10.0, simulations R3, R4, R8, and R9). Percentages have been averaged over all the corresponding simulations and projections at a given evolutionary step (given by the protostar mass msink). The scales correspond to the whole map including all the scales (second column), and in concentric rings containing all the lines of sight with radial distances to the protostar in the interval indicated in the header of the table. All the individual recovery rates are given in Table A.1.
