Notes. Radiation from a nonrotating central star of radius R in Schwarzschild spacetime as recorded by an observer in orbit of radius r. The approximate optical radius in degrees (°) of the star given by Infinity is in satisfying agreement with the star optical radius given by the formula in Abramowicz et al. (1990). We also see the errors percent of the code calculations of the stress–energy tensor compared to the relevant formula of the aforementioned work.
