On a new method to analyse QSO spectra
  A new method of analysis of QSO spectra, usually referred to as the "Thong
method", has been recently presented and made use of in a number of
publications. Several of these have been withdrawn because the authors have
been convicted of plagiarism. However, there exists no publication showing that
the method itself, which is an original contribution of the authors, is wrong.
The purpose of the present note is to show that it is and that the results
obtained when using it, including limits on the time variation of the fine
structure constant many times smaller than published by other authors, must
therefore be ignored and discarded.
