Practical implementation of the sine condition test.

The effectiveness and predictability of the sine condition test (SCTest) as an alignment technique is explored and demonstrated. This paper shows the experimental results of an alignment of a three-mirror telescope using the SCTest. We discuss the results of this alignment and compare the predicted behavior with the measured behavior. The experimental results match the predictions to within the expected errors in the process. This practical implementation shows that the SCTest is an effective tool for system alignment and that the results can be accurately predicted.
