Description:
 def angledependentabsorption(twotheta, transmission):
 """Correction for angle-dependent absorption of the sample Inputs: twotheta: matrix of two-theta values transmission: the transmission of the sample (I_after/I_before, or exp(-mu*d)) The output matrix is of the same shape as twotheta. The scattering intensity matrix should be multiplied by it. Note, that this does not corrects for sample transmission by itself, as the 2*theta -> 0 limit of this matrix is unity. Twotheta==0 and transmission==1 cases are handled correctly (the limit is 1 in both cases). """
