2.   Administration officials said the two tests would allow them to evaluate the accuracy of plans to use sampling.

3.   In both tests the bureau will use sampling to evaluate the accuracy of each method.

4.   It will also provide information that will allow air traffic controllers to evaluate the accuracy of signals from all satellites in the system.

5.   Maybe someday we can gather, possibly at a homecoming, to evaluate the accuracy of those memories.

6.   But an infrared camera to be installed on the Hubble next year could provide enough information to evaluate the accuracy of the distance estimates, he said.
