Other Packages

PyDIS is not the only game in town for analyzing astronomical spectra using python, and is far behind other tools in some areas! Here is a list of other known related packages:

Reduce Raw Data

• PyDIS: reduction toolkit for DIS on the APO 3.5-m
• specreduce: reduction software for optical spectra, from raw data to 1-d spec
• pyspectrograph: tasks for modeling a spectrograph end-to-end, and analyze the raw data. Very powerful, but complex
• pysalt: Python/Pyraf package for reducing and analyzing SALT data
• pyhrs: Software for reducing observations from the SALT High Resolution Spectrograph
• longslit: by Adrian Price-Whelan

Manipulating Reduced Data

• specutils: Affiliate package for astropy. Useful for I/O, plotting, and some analysis of reduced spectra
• spectral-cube: reading and writing spectral data cubes
• specviz: STSci package in development for visualizing 1-D spectra

Analyze Reduced Data

• pyspeckit: analysis and line/feature fitting toolkit for reduced spectra
• PHEW: Python Equivalent Width fitting tool, using pyspeckit as backend and Monte Carlo for fitting
• pysynphot: STSci package for generating synthetic photometry from spectra
• Starfish: tools for inference and fitting on high resolution spectroscopic data
• sick: inferring astrophysical parameters from noisy spectra
• lsst_sims_photUtils: tools for converting spectra to magnitudes and calculating signal-to-noise.
• linetools: A package for the analysis of 1d astronomical spectra, especially quasar and galaxy spectra.
• ppxf: Penalized pixel fitting to extract stellar or gas kinematics or stellar pops from galaxy spectra.
