A proper analysis of error propagation requires having a reasonable model ''M<sub>p</sub>'' that relates the measured signals ''s'' to the corresponding physical parameters ''p''.
A proper analysis of error propagation requires having a reasonable model ''M<sub>p</sub>'' that relates the measured signals ''s'' to the corresponding physical parameters ''p''.
Such a model can initially be rudimentary, implying the probable existence of large systematic errors.  
Such a model can initially be rudimentary, implying the probable existence of large systematic errors.  
The systematic observation and analysis of the results ''p'' and their properly propagated random errors ''p'', and their comparison with similar results from other diagnostics should allow improvement of the model, thus reducing the systematic error and improving the agreement between independent measurements (and/or models).

This gradual improvement of the physics model is the basis of scientific progress.
