Geoid-predictions and error-estimates.

All units of geoid data are m.
Results using data (56878 gravity anomalies) from whole area:
Obtained 2005-10-14 using geocol17a. Normal equations stored in 17 blocks of size 1000 KB. Equations solved on goce.gfy.ku.dk in 3 days.
Latitude interval:
64 - 72 , 64 - 72, error
73 - 80 , 73 - 80, error
81 - 89 , 81 - 89, error
Typical job-file for prediction
Also 10 parameters (gravity survey biases) were solved for.
Paarameter type code: 13 for gravity anomalies and last digits survey ID number.
