About sagui

sagui is a photometric counterpart to capivara. The package keeps the general IFU segmentation logic, but it shifts the focus from representative median spectra to region-integrated photometric SEDs with uncertainty propagation.

This makes it useful for workflows where segmentation is only the first step, followed by:

• SED fitting
• region-wise flux integration
• stellar population analysis
• property-map generation

COIN Toolbox

sagui is part of the broader COIN Toolbox effort to provide open, reusable tools for astronomical inference, statistical modeling, and data-driven workflows.

The COIN identity is community-oriented, method-focused, and designed to support reproducible science.

Design Principles

• concise public API
• robust defaults for real IFU cubes
• standalone transforms that can also be called inside segmentation
• clear separation between segmentation and region-level summaries
• optional acceleration without forcing heavyweight dependencies
