Hi:
I am confused by a idea for a long time, and it maybe an easy question.
That is, if a cryst with p1 spacegroup, after 360 degree data collection,
what the redundancy should be? I was told that it is 2, and the 2 are
F(h,k,l) and F(-h,-k,-l), but I think if the reciprocal lattice rotated 360
degree, it must intersect with the ewald sphere 2 times--for example,
go into the sphere and go out--then F(h,k,l) should be collected twice.
I donnot know what is wrong with my option. Anyone can tell me the
reason? Thanks!

Li Yang
