This paper presents a systematic study of the properties of spectra generated by transverse undulators in storage rings. These include far field intensity spectra, polarization profiles, and phase space effects. A systematic presentation of the omega-theta plot is made and practical formulas are given for estimating phase space emittance effects in the far field. First, the above parameter studies are done for transverse undulators with ideal sinusoidal trajectories, then several results for actual, real life trajectories are presented. Brief discussions of the limitations of prior undulator modelling are also given.
