Simple column format

A convenient ASCII format saves data in a self-explaining matrix. The old style has a verbal header:

YYYY MM DD HH MM SS     HAN X   HAN Y   HAN Z   NUR X   NUR Y   NUR Z 
----------------------------------------------------------------------
1999 02 03 04 00 00    13759.4  1715.1 49852.7 14918.9  1504.5 49443.8
1999 02 03 04 00 10    13759.4  1715.2 49852.5 14919.0  1504.5 49443.9
1999 02 03 04 00 20    13759.4  1715.2 49852.7 14919.0  1504.5 49443.8
1999 02 03 04 00 30    13759.1  1715.2 49853.0 14918.9  1504.5 49443.8
1999 02 03 04 00 40    13759.4  1715.4 49852.9 14918.8  1504.5 49443.7
1999 02 03 04 00 50    13758.9  1715.1 49852.9 14918.7  1504.4 49443.8
1999 02 03 04 01 00    13759.5  1714.8 49852.9 14918.7  1504.3 49443.8

and so on.

The new style has a numeric header giving the geographic latitude and longitude of each site (in degrees). This file can be directly loaded e.g. into MatLab:

   0  0  0  0  0  0      62.30   26.65       0   60.50   24.65       0
1999 02 03 04 00 10    13759.4  1715.1 49852.7 14918.9  1504.5 49443.8

and so on.

X,Y and Z are the geographic north, east and downward components. The unit is nT. Missing value = 99999.9.
