    We present a set of new synthetic diagnostics, recently implemented in the ERO code, that were developed to facilitate direct comparisons between experiments and modeling of tokamak scrape-off-layer plasmas. The diagnostics calculate the spectroscopic Doppler shift and Doppler broadening of impurity lines of interest for any line of sight, and they also generate camera images from arbitrary viewing angles allowing for curvilinear (e.g., wide-angle or fisheye) lenses. The synthetic camera diagnostics can either replicate the distortions caused by curvilinear lenses or create a rectilinear synthetic camera image and correct the curvilinear distortions in the experimental image. Comparison to experimental data is presented.
