Magnification curves
WebThe magnification μ by a lens is inversely related to the Jacobian A of the lens equation, such that (12) The curves along where the magnification diverges, i.e. det A = 0, are called critical curves on the lens plane. The corresponding curves on the source plane are the caustics. Figure 1. Open in new tab Download slide WebBesides, its formula is: Magnification (m) = h / h’. Here, h is the height of the object and h’ is the height of the object. Besides, it can also be related to the object distance and image distance. So, it can be written as: m = -v / …

WebJan 4, 2024 · When calculating the time-lag curves or magnification curves, we assume Gaussian distributions for the components of the relative velocity v between the source and the star fields in the lens, with standard deviation of 500 km s −1 in each direction. The campaign is considered to be 20 yr, which is the typical limitation for a dedicated program.
