For measuring the distances, it should be possible to use a variant of the proposed 'formula':
true dist.y.l. = anom. vel. km,s perM.y.l.*1000 000/(25*(1+(temp/6000)^3));
But it remains to produce a good theorics of the k1 and k2; we could enlarge the parallaxes system, joined to the statistics and consider the velocity of the solar sistem ( 19,5 km/s ) or the rotational velocity of the galaxy ( 250 km/s ) but it' s necessary to clarify well the mechanism for which the half of the Hipparcos parallaxes are not usable ( negative or with very higth error ).
