Minimization of the UT1 Formal Error through Minimization Algorithms

John Gipson, NVI, Inc. Karen Baver, NVI, Inc.

The primary purpose of the IVS-INT01 sessions is the estimation of UT1. Improving the accuracy and the precision of the UT1 estimates is an important goal in the scheduling of these sessions. We previously investigated reducing the UT1 formal error through the use of the Sked scheduling program (e.g., by using new source catalogs or by changing Sked parameters). Now we are trying a new approach --- using minimization algorithms to find the hypothetical observation set that minimizes UT1. We report on our progress and on the application of our work to evaluating actual and possible Intensive schedules.
