Incidentally, as I recall, there is only an ILS on 28L, an ILS 28R approach being flown as an offset to 28L.
That may have been true once, but now they each have their own ILS:

There's also an ILS to 19L. There are only circling approaches to 10L/R, and nothing at all to 1L/R. It's very rare to see landings on 1L/R. I've seen it a couple of times. It must be quite exciting to fly in a 747. While I was waiting to take off recently (as a pax) the Blue Arrows came in to refuel, and their support C130 did a low pass on 28R then circled round to land on 1.
