Warning: academic exercise follows ;-) Perhaps if one has sufficient redundant observations and uses least squares to estimate position, one could include dip as an additional quantity estimated simultaneously from the (biased) observations. The same procedure is used to process GPS measurements where one of the "nuisance" parameters is the offset of the receiver's clock from GPS System Time, which is generally unknown. -- Richard Langley On 10-Apr-12, at 1:31 AM, Antoine Cou�tte wrote: > Still, your observations once again point out that DIP is definitely > one "weak link" in the accuracy computation chain, since even under > (quite) good conditions, dip standard deviation was already close to > 0.15/0.20 arc minute. > ----------------------------------------------------------------------------- | Richard B.
