This is done by assigning counts as in the section above (on an arbitrary scale) and corresponding predicted error bars and entering them into Gosia's file #3. The format of this file is given in the Gosia manual section XXX. |

| + | Once a fit is obtained, the accuracy can be ascertained by comparing the final values of the matrix elements with those used to simulate the data. | ||

| + | |||
| + | The precision of a desired measurement can be predicted by running a [[correlated error]] calculation following the test fit(s) to simulated data. This provides an estimate of the uncertainties expected in the actual experiment. | ||
