The IGRF95 coefficients on geomag were updated on Sept 21, 1995. Through correspondence with Charlie Barton at the Australian Geological Survey it was discovered that a difference in precision caused a rounding difference for the G 7 6 term, and a misplaced decimal point caused an error in the H 8 7 term. The correct values for these coefficients are: G 7 6 10. [rather than 9.] H 8 7 -17. [rather than -11.] as reflected on the geomag coefficient set. -Joy Conrad conrad@geomag.gsfc.nasa.gov ------------------------------------------------------ The IGRF95 coefficient file at this site was updated on Nov 13, 1995. -Dieter Bilitza bilitza@nssdca.gsfc.nasa.gov
