Reconstruction of Velocities in Solar Active Regions Ravindra Belur Indian Institute of astrophysics, Koramangala, Bangalore, India email@example.com Measurements of magnetic field at different levels of solar atmosphere are becoming more sophisticated and accurate. At the same time a precise measurements of the magnetic footpoint velocity is required to understand the energy flow and injection of helicity into the corona. The line-of-sight plasma velocity can be obtained from the Doppler measurements of spectral line, while magnetic footpoint velocity is obtained from techniques such as local correlation tracking (LCT) and feature finding algorithms. Recently several other methods have been developed based on the ideal induction equation. In this talk, I will discuss the several methods developed to infer the 3-components of velocities using vector magnetic field measurements. The comparison of various integrated quantities computed from the velocities obtained from these methods will be described. I'll also discuss the recent results obtained based on several apodizing window functions used in LCT and how they are applied to the simulated data sets.
