Spherical Astronomy Problems And Solutions -

To correct for aberration and refraction, astronomers use formulas that describe these effects, such as the Lorentz transformation for aberration and the refractive index of the atmosphere for refraction. By applying these corrections, astronomers can obtain accurate positions of celestial objects.
