 \title{Two component error model}
-\description{
-  Function describing the standard deviation of the measurement error 
-  in dependence of the measured value \eqn{y}:
-
-    \deqn{\sigma = \sqrt{ \sigma_{low}^2 + y^2 * {rsd}_{high}^2}}
-    {sigma = sqrt(sigma_low^2 + y^2 * rsd_high^2)}
-
-  This is the error model used for example by Werner et al. (1978). The model
-  proposed by Rocke and Lorenzato (1995) can be written in this form as well,
-  but assumes approximate lognormal distribution of errors for high values of y.
