- W2746193612 abstract "The detection and elimination of outliers in VLBI observations is an important pre-processing step for VLBI parameter estimation. A common technique to handle this problem is based on a so-called 3-sigma rejection criterion. It starts with an initial least-squares adjustment. Afterwards, all observations are eliminated from the data whose residuals exceed their respective standard deviations (sigma) by a factor greater than three. The final parameters are estimated in a second step. This technique which is also implemented in the VLBI processing software OCCAM LSM 5.0 is compared in this study with several robust estimators which are less restrictive regarding data elimination. From a methodological point of view all considered techniques are least-squares estimations using iterative reweighting. Data from more than 2000 VLBI sessions over a time span of 20 years were used for performance tests. The following results can be given: The 3-sigma criterion is rather fast but usually too simplistic since it tends to wrongly eliminate correct observations. Among the robust estimators the BIBER by Wicki performed best. It proved to be both efficient and reliable." @default.
