exponent, the pinning model and the angular dependence of J local c . Moreover J$_{c}$ ( B ) is usually not available over four orders of magnitude. Note on the other hand that B ‖ ρ $_{=0}$/B ab c2 is different (0.7, 0.8, and 0.91 for γ / α$_{t}$ = 5 / 34 . 5 $^{◦}$, 4 / 30 $^{◦}$, and 3/20.8$^{◦}$, respectively), which cannot be seen in Fig. 5 due to the normalization. The knowledge of the upper critical field is therefore vital for the distinction between γ and α$_{t}$ . Unfortunately, the metal sheath of tapes usually masks the onset of the transition 16 and must be removed for the determination of B$_{c2}$ . 

The anisotropy of the critical current is strongly field dependent (inset in Fig. 5) and diverges at B ⊥ ρ =0 ( B$_{ρ}$$_{=0}$ in orthogonal orientation). At fixed reduced field, B/B$_{ρ}$$_{=0}$ , it is not very sensitive to changes of the parameters, as long as the B$_{ρ}$$_{=0}$ -anisotropy is kept constant and is, therefore, also not appropriate for a (simultaneous) determination of γ and α$_{t}$ . Since the field dependence of the critical current anisotropy scales with the upper critical field, the critical current anisotropy is also temperature dependent, because the reduced magnetic field increases with temperature at fixed magnetic field ( B$_{c2}$ decreases). 

The angular dependence of J$_{c}$ is presented in Fig. 6. The same combinations of γ and α$_{t}$ as for the field dependence of J$_{c}$ were used. Data at the same reduced field, b = B/B ‖ ρ =0 are compared. The differences between γ = 4 and γ = 5 are small, but the curve for γ = 3 differs more significantly, which favors the analysis of texture from angular resolved measurements of J$_{c}$ . However, the higher degree of modeling (pinning mechanism, percolation cross section,
