A time-dynamic temperature profile (TPF) enables you to specify the body temperature of an EOIR object based on the scenario time. Each pair of numbers is a scenario time and a body temperature in increasing time order on a single line separated by a tab. The temperature between samples are linearly interpolated so any high-frequency changes must be sufficiently sampled to be captured in the simulation. Lines with a leading hash mark are comment lines, enabling you to insert internal documentation or notes.
| Parameter | Units | Description |
|---|---|---|
| Time | [s] | The scenario time in epoch seconds |
| Temperature | [K] | The average body temperature of the EOIR object, in degrees Kelvin |

This example is for a model sine wave that oscillates with a full 24-hour period, or 86,400 seconds, at an average value of 250° Kelvin. It ranges from a minimum of 200° Kelvin to a maximum of 300° Kelvin. According to this TPF, the body temperature of the designated EOIR is sampled every two hours, or 7,200 seconds, and with linear interpolation the object would oscillate as shown in the graph below over the 24-hour scenario time period.
