Function to create Restricted 2PN Waveform in Fourier Domain
Input: fvec = Row vector of positive DTFT frequencies
t = Time of arrival in seconds
phase = Phase of Coalescence
fmin, fmax = minimum and maximum frequency cutoffs for the waveform
tau0, tau1.5 = Chirp-time parameters
datalen = Length of data realization in seconds
avec = Pre-calculated alpha term vector
Output: fwave = Phase term of waveform in the Fourier domain
