 ctlike generates an output model XML file that contains the values of the 
 best fitting model parameters. For all free parameters, an ``error`` attribute
 is added that provides the statistical uncertainty in the parameter estimate.
-If computation of the Test Statistics has been requested for a model component,
-a ``ts`` attribute providing the Test Statistics value is added. The output
-model can be used as an input model for other ctools.
+In addition, the entire output of the covariance matrix to a separate FITS file
+can be queried (parameter ``covmat``). The parameter order given in the file
+corresponds to the arrangement of the covariance matrix entries. If computation
+of the Test Statistics has been requested for a model component, a ``ts``
