Description

Keep the existing raw/uncalibrated columns unchanged, and add ready-to-use single-column e1/e2 with m-bias and PSF-leakage corrections already applied, for non-expert external users (galaxy-galaxy lensing, replication). Additive, so strictly-uncalibrated shapes remain available.

Research direction

Start by locating the release catalogue generation and the existing raw/uncalibrated shape columns. Determine how m-bias and PSF-leakage corrections are represented in the project before adding the calibrated single-column e1/e2 fields. Done means external users can consume corrected e1/e2 values while the existing strictly uncalibrated columns remain unchanged.
