[neutron-mc] handling of `POLARISATION PARAMETERS'

[Timur Elzhov]

Dear McStas experts,

Sorry, but I couldn't understand how the subj should be used.
I'd like to generate, say, the polarized neutron with certain
polarization in the `source' component, and then use these
components (sx,sy,sz) in the following components. But I read
in the manual,

    POLARISATION PARAMETERS (sx,sy,sz)
    This line is necessary only if the comp onent handles p 
    mo difies the spin vector. For an instrument to handle 
    required that *one* of the components contains this line.

and, "s1 & s2 in the STATE PARAMETERS obsolete and cannot be used".

I included POLARISATION PARAMETERS(sx,sy,sz) in my `source' and
simply `printf' them. I've got (0,1,0), i.e. polarized beam along
`y' axis. Well, and what? :) How can I generate polarized beam
along `z' axis (probably, by setting sy = 0 and sz = 1 in the
`source'?), and then analize them with (any) monitor?

Thanks.
