 In addition, the module \codename{QuasiLocalMeasures} implements
-certain equations from the isolated and dynamical horizon formalisms,
-as well as certain extensions defining quasi-local quantities;
-quasi-local quantities are quantities that are gauge independent, but
-depend on the choice of a particular two-sphere in a spacetime. In
-this sense, \codename{QuasiLocalMeasures} can provide
-gauge-independent measures of e.g.\ mass and angular momentum of
-regions of the spacetime enclosed in a two-sphere.

+momentum and angular momentum that have been advanced over the
+years~\cite{Laszlo04}. Even though only few rigorous proofs exist
+that establish the properties of these latter quantities, they have 
+demonstrated to be surprisingly helpful in practical situations 
+(see, e.g., reference \cite{Lovelace:2009dg}), and are therefore 
+an indispensable tool in numerical relativity.
 \codename{QuasiLocalMeasures} takes as input a horizon surface, or any
 other surface that the user specifies, such as a large coordinate
-sphere, and calculates mass, angular momentum, or other
-quantities such as the Weyl or Ricci scalars, multipole moments of the

 Finally, the module \codename{HydroAnalysis} additionally locates the
