Combining strong and weak lensing estimates in the Cosmos field

We present a combined cosmic shear analysis of the modeling line-of-sight distortions on strongly lensed extended arcs and galaxy shape measurements in COSMOS field. develop framework to predict covariance strong lensing basis small scale matter power-spectrum. The weak measurement is performed using data from survey calibrated with cloning scheme Ultra Fast Image Generator UFig (Berge 2013). by forward main deflector external components same Hubble Space Telescope imaging set. With sample three we 2-sigma detection cross-correlation signal between two complementary along identical line sight. large samples lenses available next generation ground space based observatories, probes allows for systematic checks, cross-calibration either
