 ## Quick Install
-Open `scattererTmatrix.pro` with your precompiled version of [ONELAB](https://onelab.info) to compute the T-matrix of an isolated scatterer of arbitrary shape as described in [1].

+The model `scattererTmatrix.pro` computes the scattering (T-)matrix solely and does not require any Python support from GetDP. It is quite fast and accurate since it :
 * features spherical PML
-* re-uses the factorization for each new input harmonic
+* features curved elements + high order Webb elements
+* re-uses the factorization for each new input harmonic (i.e. one single inversion to get the T-matrix)
 * computes the coefficients by integration within GetDP 
 
-The default parameters in `scattering.pro` are set to compute the T-matrix of a sphere. It retrieves the results from [1].
+The default parameters in `scattering.pro` are also set to compute the T-matrix of a sphere.
