Includes a frequency fit of shift type in the Jacobian.

Retrieval of deviations between nominal and actual backend frequencies can be included by this method. The assumption here is that the deviation is a constant off-set, a shift, common for all frequencies (and not varying between measurement blocks).

This method adds one element to the state vector (x).

• jacobian_agenda (Agenda, optional) – Pure numerical Jacobian calculations. See jacobian_agenda, defaults to self.jacobian_agenda [INOUT]

• f_grid (Vector, optional) – The frequency grid for monochromatic pencil beam calculations. See f_grid, defaults to self.f_grid [IN]

• df (Numeric, optional) – Size of perturbation to apply. Defaults to 100e3 [IN]

• verbosity (Verbosity) – ARTS verbosity. See verbosity, defaults to self.verbosity [IN]
