Description of Chirp

The unit called Chirp adds the waveform of a coalescing binary star system to the input data set and outputs it. The waveform is computed using only the lowest-order radiation reaction force on the orbit, so it is a good approximation only for widely separated binaries. The user can choose the chirp mass of the signal, the initial phase of the signal, and the start time of the signal within the input data set.
 

Using Chirp

Chirp's parameter window (double-click on the unit while holding down the Control key) is used to set the chirp mass, phase, and starting time of the chirp. The user can select whether the starting time is measured from the beginning of the input data set or according to an absolute time. The absolute time is computed from the acquisition time of the input data set.
