***********************************************

Some Notes: 

* At PTK, the induction magnetometer sensors were buried under the ground 
  on November 21, 2007.  Before that, the sensors were left on the 
  ground for test observations.  

* After December 1, 2007, the D-component at Sata is disconnected. 

* H and D components of the fluxgate magnetometer at KAG (Kagoshima) 
  are short-circuited in the cable before the data recorder for 
  September 8, 2007 - January 28, 2009.  Please do not use the 
  fluxgate magnetometer data at this interval. 

* On Jan.21-Feb.18, 2009, and Mar.28-Apr.17, 2009, a radio tramsmitter 
  worked at Magadan at 4-28 MHz and the induction magnetometer data becomes 
  highly noisy. 

*  After Oct. 25, 2016, ATH magnetometer was moved from AUGO-I to AUGSO at
  54.60N, 246.36E, and Z-component sensor was removed and replaced by the riometer
