LSST DESC software dependencies

This pipeline relies on several Python packages developed by the LSST Dark Energy Science Collaboration (LSST DESC). It integrates these DESC tools into a unified analysis workflow. We encourage readers to consult the official documentation for each project; links are provided below.
