Powder1 ComponentGeneral powder sample with a single scattering vector. No multiple , scattering, no incoherent scattering, no secondary extinction. The shape of the sample may be a cylinder of given radius or a box with dimensions xwidth, yheight, zdepth. The efficient is highly improved when restricting the vertical scattering range on the Debye-Scherrer cone (with 'd_phi'). You may use PowderN to use N scattering lines defined in a file. Example: Powder1(radius=0.015,yheight=0.05,q =1.8049,d_phi=0.07,pack=1, j=6,DW=1,F2=56.8,Vc=85.0054,sigma_abs=0.463)
