Query: Doppler effect and Hubble effect in different models of space-time in
  the case of auto-parallel motion of the observer   Doppler effect and Hubble effect in different models of space-time in the
case of auto-parallel motion of the observer are considered. The Doppler effect
and shift frequency parameter are specialized for the case of auto-parallel
motion of the observer. The Hubble effect and shift frequency parameter are
considered for the same case. It is shown that by the use of the variation of
the shift frequency parameter during a time perod, considered locally in the
proper frame of reference of an observer, one can directly determine the
centrifugal (centripetal) relative velocity and acceleration as well as the
Coriolis relative velocity and acceleration of an astronomical object moving
relatively to the observer. All results are obtained on purely kinematic basis
without taking into account the dynamic reasons for the considered effect. PACS
