sans.models.smearing_2d

class sans.models.smearing_2d.Smearer2D

Gaussian Q smearing class for SANS 2d data

__init__()

Assumption: equally spaced bins in dq_r, dq_phi space.

Parameters:

• data – 2d data used to set the smearing parameters
• model – model function
• index – 1d array with len(data) to define the range of the calculation: elements are given as True or False
• nr – number of bins in dq_r-axis
• nphi – number of bins in dq_phi-axis
• coord – coordinates [string], ‘polar’ or ‘cartesian’
• engine – engine name [string]; ‘c’ or ‘numpy’

__module__ = 'sans.models.smearing_2d'
