M3's Gooood!!

After quite a bit of fiddling around, we eventually got fringes with the big CGH!  Pretty good ones at that, so this is Huge: it means there's nothing wrong with the surface figure of M3 :) :) :)

We've now confirmed that the mirror surfaces are all fine & 3 of the 4 have been aligned - we just need to align M3 to the rest of them now...
