 Nonetheless, both peak area and peak height should be supplied to the user, hence the missing one was included as a deterministic model variable and thus still part of the model.
 In case of the normal and double normal models, the peak height $h$ was used for scaling and the area $A$ was calculated by
 
-$$\tag{10}A = \frac{h}{\frac{1}{\sigma\sqrt{2\pi}}}.$$
+$$\tag{10}A = \frac{h}{\frac{1}{\sigma\sqrt{2\pi}}}$$
 
 For skew normal and double skew normal models, the scaling parameter was the peak area.
 Since the mode and mean of a skewed distribution are – in contrast to normal distributions – distinct, the calculation of the height was nontrivial and ultimately a numerical approximation was added to the skewed models.
