 The available commands are
 
-* `enstrophy`: to compute the enstrophy, the parameter alpha and
-  alpha times the enstrophy. This command prints
-  `step_index time average_alpha average_enstrophy average_alphaxenstrophy alpha enstrophy alphaxenstrophy`
+* `enstrophy`: to compute the enstrophy and various other observables. This
+  command prints
+  ```step_index time average_alpha average_enstrophy average_alpha*enstrophy alpha enstrophy alpha*enstrophy```
   where the averages are running averages over `print_freq` steps.
 
 * `uk`: to compute the Fourier transform of the solution.
