Description
We present a weak lensing analysis pipeline developed for SuperBIT, a balloon-borne telescope that operates at ~36 km altitude, above 97-99% of the Earth’s atmosphere. SuperBIT completed its first science flight in 2023, delivering high-quality imaging at a fraction of space-mission costs. The pipeline involves stacking 300-second exposures, extracting sources, modeling the PSF, measuring galaxy shapes using Bayesian forward modelling, applying metacalibration for shear estimation, and reconstructing cluster mass maps. Our goal is to release shear catalogs for 35–40 clusters, enabling detailed studies of dark matter through multi-wavelength comparisons.
