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, will be included in future releases on a best-effort basis.
Warning
This documentation is for the most recent tag of the DAP. If you're looking for DR15 (DAP version 2.2.1) documentation, see the DR15 MaNGA Overview.
If you use the DAP software and/or its output products, please cite the following two papers:
- Overview: Westfall et al. (2019, AJ, 158, 231)
- Emission-line Modeling: Belfiore et al. (2019, AJ, 158, 160)

The MaNGA DAP software was written to be more broadely useful. The pages above provide some examples of how the code can be used more generally, beyond its application to MaNGA.
