+NLNPARAMS	integer		# Number of parameters
+NLNFPARAMS	integer         # Number of fitted parameters

+DESCRIPTION
+The values of integer, real or double  parameters are returned.
+The parameters include the number of parameters, the number of fitted
+parameters, the maximum number of iterations, the number of iterations,
+the total number of points, the current chi-squared, the previous
+chi-squared, the lambda factor, the fitting tolerance and the fitted
+scatter term.
