Synchronization Gauge Definition | What is it?

Please give me a defnition of the concept "synchronization gauge" I find in papers.

Please give me a defnition of the concept "synchronization gauge" I find in papers.

Rizzi et al, Synchronization Gauges and the Principles of Special Relativity give this definition:

"A synchronization gauge is a (very particular) group of transformations, internal to the theory, which leave the observables unchanged (”saving the phenomena”)" (page 2, footnote 3).​

Thus I interpret this to correspond to a whole family of coordinate systems available for a single observer to choose from, all agreeing the same "measurements" e.g. for observer's proper time. Examples are:

- the $\epsilon$-parameterised family of Reichenbach transformations
- the $\epsilon$-parameterised family of Mansouri-Sexl transformations
- the $\epsilon$-parameterised family of generalised Selleri transformations

(all for a fixed value of V for a given pair of observers).

A synchronization gauge is a measure used to evaluate the level of synchronization or coordination between different systems, processes, or entities. It is typically used in technical or scientific papers to assess the effectiveness of synchronization in achieving a specific goal or outcome. This gauge may take various forms, such as a numerical scale, a graphical representation, or a set of criteria for evaluation. The purpose of a synchronization gauge is to provide a standardized way of assessing the degree to which synchronization has been achieved, allowing for comparison and analysis across different contexts or studies. Overall, a synchronization gauge helps to quantify and understand the level of coordination between different elements in a system or process.
