The MaNGA Data Analysis Pipeline

Powered by Astropy Build Status Coverage Status Documentation Status License

The MaNGA data-analysis pipeline (MaNGA DAP) is the survey-led software package that analyzes the data produced by the MaNGA data-reduction pipeline (MaNGA DRP) to produced physical properties derived from the MaNGA spectroscopy.

These quantities currently include:

  • Spatially stacked spectra

  • Stellar kinematics

  • Nebular emission-line properties: fluxes, equivalent widths, and kinematics

  • Spectral indices: absorption-line (e.g., H-delta) and bandhead/color (e.g., TiO, D4000) measurements

All survey-led properties are derived from the datacubes, specifically the LOGCUBE files. However, the core functions are developed to consider each spectrum largely independently. The DAP currently focuses on “model-independent” properties. Higher-level, model-dependent properties, such as stellar-population parameters, are outside of the scope of the current pipeline.
