Astropy Tutorials

List of Tutorials

• Analyzing UVES Spectroscopy with Astropy
  This tutorial demonstrates the data analysis of MN Lup obtained with the UVES spectrograph on the VLT.
• Editing a FITS header
  Demonstrates how to read in, edit a FITS header, and then write it back out to disk using astropy.io.fits.
• Making a plot with both redshift and universe age axes
  Demonstrates how to make a plot with both redshift and universe age axes, using astropy.cosmology and matplotlib.
• Read and plot catalog information from a text file
  Demonstrates use of astropy.io.ascii for reading and writing ASCII data, astropy.coordinates and astropy.units for converting RA (as a sexagesimal angle) to decimal degrees, and matplotlib for making a color-magnitude diagram and on-sky locations in a mollweide projection.
• Using Astropy Quantities for astrophysical calculations
  Demonstrates use of the astropy.units, astropy.constants, and the Quantity object for calculating the mass of a galaxy from its velocity dispersion and determining masses of molecular clouds from CO intensity maps. Includes use of matplotlib for making a histogram and an image with a colorbar. Also includes good practices for using quantities in functions you might distribute to other people.
• Using astropy.coordinates to Match Catalogs and Plan Observations
  Demonstrates use of astropy.coordinates for common tasks. Includes matching catalogs against each other, basic observing planning tasks, and basic usage of coordinates.
• Viewing and manipulating FITS images
  Demonstrates use of astropy.utils.data to download data; astropy.io.fits to open the file; matplotlib to view the image with different color scales and stretches and to make histrograms. Also includes method for simple image stacking.
• Viewing and manipulating data from FITS tables
  astropy.utils.data to download the file, astropy.io.fits to open and view the file, matplotlib for making both 1D and 2D histograms of the data.
