    Data normalized to 100 for March 1987. This file contains the latest corrections for long-term stability, done on 10 December 2010, and it is recommended that this one should be used for long-term studies. Other variants of the data files do not yet contain this latest correction. This latest correction is for SANAE and SANAE NMD, increased by +2% since April 1997, and it will be explained in a paper at the 32nd ICRC in 2011
