From Matter Density to Deflection Angle and Gravitational Lensing Using a Perturbative Method

Year: 2025

Type: preprint

Abstract: Here we have uploaded all the codes required for the computations in the paper. The calculations of the formulas and the generation of the figures in the paper were all carried out using these codes. For the case that the matter distribution can extend to spatial infinity, all codes are in the folder named "Infinite_codes". For the case that the matter exists only within a finite range, all codes are in the folder named "Finite_codes". All figures used in our work are all in the folder named "Figures".
