However, I doubt that you will often need on which components the points really lie. It is easy to test if two points lie on the same component (the difference has good reduction). Operations and comparisons on a group of the form $\mathbb{Z}/2 \times\mathbb{Z}/2$ does not need any thing else. In particular the monodromy pairing etc can be terermined completely using just this test. | |
