Indeed, the ramification is on $N$ times the number of sheets in $S_1$ points. If we could somehow reverse the order of the arrows $S' \to S_1 \to S$ it would be OK, but I don't think that's right, the cover is Galois but not necessarily abelian. | |

If it doesn't, then is there an analogue? Also, would the branching index of $S^{'}$ not be $N$ times the number of sheets in $S_1$? | |
