Introduction

The SAGE-analysis package was developed to handle the data products produced by the SAGE model, available here.

Why Did We Create A New Repo?

SAGE is an extremely modular and flexible semi-analytic model. The base model (presented in Croton et al., 2016) has been adjusted and altered to answer a number of science questions on a variety of topics including galactic HI and angular momentum properties in DARK SAGE, the Epoch of Reionization in RSAGE, and the star formation history and galactic dust in DUSTY SAGE _.

Due to the wide array of science that SAGE can cover and the number of models that spawned from its development, there has been a need to develop a framework to ingest in data from (ideally) any SAGE variant. This repo represents such an effort. It represents a series of modules intended to provide the easy ingestion and analysis of the base SAGE data, whilst serving as a template for analysing any other SAGE flavours.

Advantages of the Package

• Easy analysis and plotting of multiple different SAGE models. For example, comparing SAGE models with/without supernova feedback.
• Memory efficient analysis of SAGE output. All calculations are performed using only a single output file at a time, ensuring no extra memory overhead associated with opening many files.
• Support for the user to implement their own functions to analysis + plotting.
• Template for creating custom data classes to ingest any arbitrary SAGE data output. Useful if you’re looking to develop using SAGE.
