Spectroscopic Data Reduction and Analysis¶
General Tools¶
- specutils - An Astropy coordinated package for astronomical
spectroscopy
- Provides a shared set of Python representations of astronomical spectra and basic tools to operate on these spectra.
- linetools - This is a package for the analysis of 1d astronomical
spectra, especially quasar and galaxy
spectra
- Still under development. Its core developers work primarily on UV/optical/IR absorption line research, so most of the functionality is aimed at the identification and analysis of absorption lines. The eventual goal is to provide a set of tools useful for both absorption and emission lines.

Visualization¶
- specviz - An interactive astronomical 1D spectra analysis
tool
- Made by STScI. An gui-based interactive analysis tool for one dimensional astronomical data using Python.
- cubeviz - Data analysis package for
cubes
- Made by STScI. CubeViz, a visualization and analysis tool for data cubes from integral field units (IFUs). Online document is here
Data Reduction Pipeline¶
- Pypelt - The Python Spectroscopic Data Reduction
Pipeline
- PypeIt is a Python based data reduction pipeline (DRP) written oringinally for echelle spectroscopy and since expanded to low-resolution spectrometers.
- arclines - Database of arc lines from optical-IR spectrographs
- MaNGA data reduction and analysis pipeline
- mangadap - The MaNGA Data Analysis
Pipeline
- 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.
- mangadap - The MaNGA Data Analysis
Pipeline
- GIST - Galaxy IFU Spectroscopy
Tool
- A convenient, all-in-one framework for the scientific analysis of fully reduced, (integral-field) spectroscopic data.
- TDOSE - Three Dimensional Optimal Spectral
Extraction
- Python pipeline to extract spectra of both point sources and extended sources from integral field data cubes
- pydis - A simple longslit spectroscopy pipeline in
Python
- The goal of pyDIS is to provide a turn-key solution for reducing and understanding longslit spectroscopy, which could ideally be done in real time. Currently we are using many simple assumptions to get a quick-and-dirty solution, and modeling the workflow after the robust industry standards set by IRAF.
- speclite - Lightweight utilities for working with spectroscopic
data
- By David Kirby. This package provides a set of lightweight utilities for working with spectroscopic data in astronomy.
Redshift or Radial Velocity Measurement¶
- grizli - Grism redshift & line analysis software for space-based
slitless spectroscopy
- By Gabriel Brammer.
- redrock - Redshift fitting for
spectroperfectionism
- This is DESI’s redshift measurement tool
- redmonster - Python utilieties for redshift
measurement
- redmonster is a project to develop a sophisticated and flexible set of Python utilities for redshift measurement, physical parameter measurement, and classification of one-dimensional astronomical spectra.
- Originally designed for eBOSS and the paper can be found here
