=== Taking Data ===
The method of starting oscillations described in the section above should allow data to be taken in a given orientation. As described in the [[Theory]] section, a number of period measurements is required to even be in the ball park of the accuracy required. A large number of measurements should be taken in each orientation and each orientation should be measured a number of times.

As outlined above, recording the oscillation angle as data taking begins allows the small angle correction to be made. Similarly, retaking this measurement at the end will indicate the amount of degradation which has occurred during the run. This information can be used to interpolate the angle of oscillation midway through the run or to calculate a small angle correction for each data point.
