| Description: | Lookup table for x-axis value |
Variable Lookup x defines the x values for a look-up table used to translate raw sample values to final values used in the simulation. This is a multi-band property used in conjunction with Lookup y and optionally Lookup Unit. Sample values that fall between the lookup table x values are linearly interpolated into y values. Values that fall outside the range of defined x values are truncated to the nearest y value.
Example:
| Property | Value | Units | Band |
|---|---|---|---|
| Lookup x | 1 | - | 1 |
| Lookup x | 5 | - | 2 |
| Lookup x | 10 | - | 3 |
| Lookup y | 6 | - | 1 |
| Lookup y | 35 | - | 2 |
| Lookup y | 28 | - | 3 |
| Lookup Unit | 1000 | - | 1 |
A raw sample value of 3 is first translated to 20.5 (linear interpolation between y values 6 and 35) and then divided by 1000 (lookup unit) to obtain the final value of 0.0205.
