Add Time Of Flight Intervals¶

Add intervals for the time of flight calculation.

Each [ertStart, ertStop) interval contains a polynomial function used to compute the time of flight for the given ert. The intervals can overlap and are sorted in descending order of the start time. The first (highest start time) interval where the requested ert fits, will be used for the calculation.

The formula used for calculating the time of flight for a frame/packet received at ert in the [ertStart, ertStop) interval is:

delta = ert - ertStart

tof = polCoef[0] + polCoef[1] * delta + polCoef[2] * delta^2 + ...

The result of the polynomial is the tof expressed in seconds.
