An observer is interested by the physical properties (line frequencies,
velocity of the gas) of a source in its own reference frame. However, the
observations happen in a different frame, namely the topocentric frame
for ground-based observations. This implies a change of frame to infer
the physical properties in the source frame from the measured frequencies
in the measurement frame. Several difficulties arise in astronomy: 1) the
Earth ... To be completed.
