Data quality flags can take one of the following values :
automatic quality control procedures: 0=good 1=suspect 2=bad 3=not controlled
manually added flags: 5=good 6=suspect 7=bad 8=estimated 9=missing or not
controlled
Quality control procedures are explained in the document GTS_QC_handbook.ps that
can be found on the FASTEX anonymous ftp serveur (cnrm-ftp.cnrm.meteo.fr), in
the directory pub-fastex/doc
