commit 684c7e944f3aa5ef0613900e5a234fabe92a7827

    Book: minor editing to help in readability
    
    Of the sentences in the book started with the number '20' and the previous
    sentence ended in a '4'! This structure was hard to read and could cause
    confusions.
    
    With this commit, the '20' is changed to 'Twenty'. This helps visually
    separating the sentences.
    
    This issue was reported by Thérèse Godefroy.

+Twenty years later in 1968, J. L. S@'ersic showed that @mymath{n} can have a 
variety of values and does not necessarily need to be 4.
 This profile depends on the effective radius (@mymath{r_e}) which is defined 
as the radius which contains half of the profile brightness (see @ref{Profile 
magnitude}).
 @mymath{I_e} is the flux at the effective radius.
 The S@'ersic index @mymath{n} is used to define the concentration of the 
profile within @mymath{r_e} and @mymath{b_n} is a constant dependent on 
@mymath{n}.
