Field | Definition | Type | Default |
---|---|---|---|
TID | Table identification number. | Integer > 0 | Required |
X1 | Table parameter. | Real | 0.0 |
xi, yi | Tabular values. | Real | Required |

where x is input to the table and y is returned. The table look-up is performed using linear interpolation within the table and linear extrapolation outside the table using the two starting or endpoints, see Figure 1. No warning messages are given if table data is input incorrectly.
