DecUnation results are the mean of the max. and min. for the day in question 

 corrected for index error as determined at Agincourt. 



Inclination results are the mean of the observed values. No correction for 

 index error has been applied as this changes with magnetic latitudes. 



Horizontal Force results are the mean of the values determined independently 

 by the magnetometer and total force instruments, and are corrected for index 

 error to Agincourt standard.
