Descripción
A model is given for constructing artificial integrated spectral lines
which allows the inclusion of all effects relevant to the synthesis of
these lines by numerical methods. Among the effects included are
noise, limb darkening, the centre-to-limb variation of the shapes and
wavelength positions of the spectral line profiles, different laws of
the differential rotation and a tilting of the rotating star.
Fourier transformation of the artificial integrated spectral lines is
applied to decide whether the different effects may influence the
possibility of detecting stellar differential rotation by the method
of Gray (1977).
