Sergey,
You wrote: "analogy (is inapplicable) for deducing of quantity Mvc( 1-u/c) since speed v is measured in the Earth reference frame and speed of the Earth u - in the Sun reference frame, i.e by different observers".
The reference frame interpretation is incorrect. It is in fact a gross misinterpretation of the experimental data (see below) which Lorentz used in discerning the Lorentz transformation. The reference frame interpretation is a fantasy and introduces a fantastic illusion into science to create a makeshift working hypothesis to overcome the problem Lorentz faced as stated below.
I refer you to Lorentz 1904 paper, in which he iterated the data of Kaufman's experiments on fast moving electrons (on Earth!!), and by trial and error he discerned the EMPIRICAL EQUATION which we now know as the "Lorentz transformation". If you read the opening lines of Lorentz' paper, you will find that the "observer on earth" that is data obtained for the motion of a particle (which was expected to move at velocity v) with respect to the lab frame contains a term involving Earth's motion of velocity u.
Lorentz wrote in the burning problem he faced in the opening paragraph: "The problem of determining the influence exerted on electric and optical phenomena ..... IN VIRTUE OF THE EARTH'S ANNUAL MOTION ...." (p. 11)
Then in art 2. The experiments (Rayleigh and Brace, Trounton and Noble) of which I have spoken are not the only reason for which a new examination of the PROBLEMS CONNECTED WITH THE MOTION OF THE EARTH is desirable.(p.12)
The problem was just like the background temperature field (of temp T2) in the hierarchy influence the heat (S1T1) generated within it, by usurping a fraction of it, the background "velocity field" of velocity u, was found to influence the energy Mvc by usurping the fraction.
But Lorentz problem was: It "admits a simple solution, so long as only ....the first power of of the ratio between the velocity of translation (of Earth) u and the velocity of light" is taken into account.
So he means that if the term is Mv( 1-u/c) the solution to the problem is simple. But it is Mv(1-u/c)/(1 - u2/c2) the solution becomes difficult.
"Cases in which quantities of the second order, i.e. of the order u2/c2 may be perceptible, present more difficulties".
This difficulty was overcome in SRT by merely postulating that time t changes to t' = t(1- xu/c2)/(1-u2/c2)1/2. If this contention has any validity, then this equation should have been verified by experiment. Can you tell me at least one experiment which has verified the above equation? If this is not verified, then the two reference frame hypothesis falls.
