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.

• 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
