* R1, Lon1, and Lat1 are radius, longitude, and latitude of the larger spot. R2, Lon2, and Lat2 are the same for the smaller spot. The spot temperature is the same for both spots and is expressed in units of the photospheric temperature, $T_{\rm sp}/T_{\rm ph}$, as well as in Kelvin degrees. The difference $\Delta T=T_{\rm ph}-T_{\rm sp}$ is also listed. The total spot area, $A_{\rm rel}$, is expressed in percent units of the star surface.
