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 will be linearly interpolated so any high frequency changes must be sufficiently sampled to be captured in the simulation. Lines with a leading hash mark will be skipped to allow 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.

Here is an example of a model sine wave that oscillates with a full 24-hour period or 86,400 seconds at an average value of 250° Kelvin and 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 2-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.
