- | ===== Formula ===== | + | ===== Baseline Correction ===== |

- | To perform integration you should specify two columns: //x// and //y//. | + | If your initial data to be integrated contains a baseline (usually constant or linear), you may want to subtract it from data **before** integrating. (A constant baseline will result in linearly growing integral.) |

- | The result of integration is the column with integral values. Integration is performed using the formula: | + | In such case the algorithm may be the following: |

+ | - Create Fit Plot with your initial table data | ||

+ | - Add a Fit Curve which simulates the baseline. You may specify a custom equation (Pro edition only) | ||

+ | - Specify Fit Interval so that it contains only noise points | ||

+ | - Fit the data by clicking '' | ||

+ | - Subtract the baseline fitting curve from data by checking '' | ||
