Method Details

calcProfile(self, maxQ=None, dz=None)

source code


calculte the profile from model
dz (Angstrom)
    the step size for the profile.
maxQ (inv Angstrom)
    the maximum desired Q.  This is equivalent to dz = 4*pi/maxQ.
dz default to 1 angstrom profile steps if neither maxQ nor dz are given

layer(self, name, depth=100, rho=0, mu=0, phi=0, theta=270)

source code

model.layer('name',depth,rho=0,mu=0,phi=0,theta=270) Add a layer to the model for all profiles. The layer can be flat (give either the value or a range), it can be 'join' indicating that it should extend the preceding layer of the same profile by the depth of the new layer, or it can be layer constructor such as spline(n,[lo,hi]).

interface(model, width)

source code

set the interface width between layers. The width specifies one standard deviation of a Gaussian smearing function.
