## 3. Example

From the adjusted network of Chapter E Section 6, Figure G-13, determine the standard error ellipse and 95% CI for each adjusted point.

Figure G-13 Adjusted Network |

The network had three DF and a S_{o} of ±2.136'. The last covariance matrix was:

### a. Sub-Matrices

### b. Az_{U} of Each Error Ellipse

*Point J*

*Point K*

### c. Rotated Covariance Matrices Diagonal Elements

*Point J*

*Point K*

### d. Standard Error Ellipse Parameters

*Point J*

*Point K*

### e. 95% CI Error Ellipse Parameters

Table G-2: At 3 DF, F Statistic = 9.55

*Point J*

*Point K*
