No: tired light is no a coherent process while the CREIl is space-coherent.
Atmosphere refracts the light by a space-coherent scattering process which does not destroy the wave surfaces. The CREIL is a perturbation of the refraction produced by a Raman type resonance, it is space-coherent. The main argument against "tired light" and Wolf's shifts is that they apply to time-coherent light, so that these theory are necessarily space-incoherent. The CREIL contains the parameter "time coherence" which must be "smaller than all relevant time constants", the collisional time of the gas and a Raman resonance (quadrupolar) period.
Experiments made with lasers (named "Impulsive stimulated Raman scattering") have exactly the same theory than CREIL, they differ from it only by the order of magnitude of the time constants.<blockquote id="quote">quote:<hr height="1" noshade id="quote">

The anomalous "acceleration" is deduced from the frequency of the received radio signals which appears too high. The CREIL explanation is very simple: beyond 10 UA, the protons of the solar wind combine with electrons, making excited hydrogen atoms.

The waste explanation would not change with the distance, except from a decrease of the radioactivity of the plutonium. If it is disgassing or leaks of gas, it would not be the same for all probes.

I wrote an error: it is a division by a factor much closer to 1. The CREIL is a theory of usual electromagnetism, it does not postulate anything about the speed of the light.

TVF, Its the Hubble Constant and not the rate of expansion that this anomaly is close to. The Hubble Constant is measured in the real world and expansion rate is from a model. Two very different things.

Here is, briefly, the theory of the refraction:
The electromagnetic waves (in particular light) propagate in the vacuum. If we put atoms in this vacuum, they are excited, and if they do not absorb, they reemit the absorbed energy by a field delayed of (pi)/2 (Rayleigh coherent field). If the number of atoms is large enough, Huygens construction works, so that the delayed fields add to make wave surfaces identical to the wave surfaces of the exciting light. The interference of exciting and scattered light produces a field slightly late, named refracted field.
In the CREIL effect, in a first approximation, the Rayleigh coherent field is replaced by a Raman coherent field; but, as the Raman frequency is not equal to the exciting frequency, a phaseshift appears. Avoiding too large a phaseshift is at the origin of Lamb's condition.

Space-coherence means that the wave surfaces are not perturbed locally, so that it is possible to make images.
In the refraction, the Huygens construction is not perfect, so that the wave surfaces get small local perturbations.The mean wave surfaces produce the images, the perturbations produce the incoherent Rayleigh scattering.

Time-coherence means that a source does not emit a perfect sin wave (really it is strictly, physically impossible). It is possible, with a good approximation to suppose that usual (not laser) sources emit pulses, the length of which is of the order of a nanosecond.
The "Impulsive stimulated Raman scattering" (ISRS) has exactly the same theory than the CREIL, but it uses femtosecond laser pulses. Applying Lamb's condition, the relevant time constantsmust be about 100000 times shorter in CREIL than in ISRS. This decreases enormously the effect: decreasing the collisional time of the gas decreases proportionally the CREIL, the CREIL is proportional to the square of the period of a Raman resonance obeying Lamb's condition, thus the shift is decreased by a factor 10 power-15: astronomical paths are needed for a good observation.

The fuzziness is a consequence of the lack of space-coherence: if the wave surfaces are destroyed, it does not remain images.

No. A maser piloted frequency is sent from the Earth, multiplied on the Pioneer by a fraction of integers, and sent back, compared with the maser frequency. A lot of corrections are done, for instance the acceleration from the Kuiper belt, the pressure of radiation of the sunlight...

The coherent effects are much stronger than incoherent: in a pool, through 100 metres of water, you see images with acceptable fuzziness and weakness. The refraction in water delays the waves of (pi)/2 after a path of the order of 10-6 metres (compute it exactly !), that is light was absorbed then reemitted each micrometer. The coherent absorption is about 10+8 stronger than the incoherent.
The anomalous frequency shift of the Pioneer probes is at the limit of detection. I am unable to give a precise result because I do not know the tensor of polarisability of excited atomic hydrogen, and I do not know the density of the solar wind.

Tom, I'm wondering about another possible measure of the distance of the cosmic microwave "background":

Assuming that the "variations" in the CMB are actual structure and not statistical noise, how nearby would the CMB have to be in order to observe parallax in these variations?
