As you say, the two are related but look different, and the intensity on
the subsequent images look different too
However there are some default scaling parameters, and I have no idea what
they are..

Any alternating strong/weak pattern should generate a strong off-origin
peak in the native Patterson . Is there such a feature?

The cell dimensions are rather symmetric a~= c; beta ~= 120?
Is there an alternative Space group?
