At R = 0 {\displaystyle R=0} , I ( R = 0 ) = I e ⋅ e 7.67 ≈ 2000 ⋅ I e {\displaystyle I(R=0)=I_{e}\cdot e^{7.67}\approx 2000\cdot I_{e}} Thus, the central surface brightness is approximately 2000 ⋅ I e {\displaystyle 2000\cdot I_{e}} .
При R = 0 {\displaystyle R=0} I ( R = 0 ) = I e ⋅ e 7.67 ≈ 2000 ⋅ I e , {\displaystyle I(R=0)=I_{e}\cdot e^{7.67}\approx 2000\cdot I_{e},} то есть поверхностная яркость центра галактики составляет приблизительно 2000 ⋅ I e {\displaystyle 2000\cdot I_{e}} .
