Various approximations of the Doppler effect

The Doppler effect expresses that a source emitting in its rest frame at a frequency \ensuremath{f_\ensuremath{\mathrm{}}^{\ensuremath{\mathrm{rest}}}} will appear to emit at a frequency \ensuremath{f_\ensuremath{\mathrm{}}^{\ensuremath{\mathrm{obs}}}} in the observation frame, which depends on the velocity of the source in the observation frame, \ensuremath{v_{\ensuremath{\mathrm{}}}^{\ensuremath{\mathrm{obs}}}}. Sections 1.3 and 1.4 will show how this property can be used to interpret the spectral axis measured in the observatory frame in terms of the property of the source in the source rest frame.
