Reducing astronomical data to find gravitational microlensing event Banafsheh Adami b adami@ph iut ac ir Sep 2018 Department of Physics Isfahan University of Technology Isfahan 84156 83111 Iran University Code IUT 77142 Degree M S c Language Farsi supervisor Dr Sedigheh Sajadian s sajadian@cc iut ac ir Abstract Data reduction is one the most important process of researches in astronomy and astrophysics Data reduction includes all steps which convert the crude astronomical images to the astrophysical events These steps are similar for different astronomical events in which the brightness of one star changes with time although they may be different in some details This paper will help for learning or even doing data reduction of each astronomical events Data reduction of microlensing events contains 7 stages in which first the crude images will be calibrated Then some of the best calibrated images will be chosen for making the reference images The reference image helps for comparing all taken images to indicate how the source light changes versus time For this propose all images should be registered to the reference images Then all images should be taken to the same scale Finally the resulted images will be subtracted from the reference image to find the light curve of the desired source star Keywords Data reduction gravitational microlensing
