Read Abstract +

The quantitative evaluation of the models for correcting astronomical atmospheric refraction is very important for actual astronomical observation applications. In this work, six astronomical atmospheric refraction correction models are reviewed, including the linear model, the exponential model, the double exponential model, the Hopfield model, the accurate segmented model and the astronomical atmospheric refraction series expansion model. The systematic errors and random errors of the models are calculated for comparison. The application scope of each model is given for future applications.¹
