(14) Exponential disc scale length. (15)–(17) Convergence factor for the j_*, j_gas and j_bar profiles. The complete version of this table is available at the CDS. ^( † )These convergence criteria should be seen as an indication of the convergence of the j profiles rather than taken at face value to predict the exact value of j. In addition to this, values below 0.7 should be taken with extra caution as we find them to be low not necessarily because they are very far from convergence, but because they rely on an extrapolation of a polynomial that it is usually monotonically increasing for those profiles. Along this paper we used ℛ ≥ 0.8 to define a j profile as convergent.
