Veusz: A Python-Based Interactive Plotting Package

by Kelle July 26, 2010

This is a guest post by Jeremy Sanders about the plotting package he’s developed. Jeremy is a postdoc working in the X-Ray Group at the Institute of Astronomy in the University of Cambridge in the UK.

Veusz (pronounced “views”) is a python-based GUI plotting package that I (Jeremy Sanders) have developed. As an astronomer, I was [...]

Manipulating and Viewing FITS Files in Python with pyds9

by Jessica July 14, 2010

For anyone who uses python and ds9 to visualize their FITS files, I think pyds9 is now a must-have. It is officially written and developed through SAOImage ds9 so it will be supported for the long haul. Here are the primary links to get going:

TARball for installation: Source
Documentation for installation and use: Docs

The documentation is [...]

Interpolation and Integration in Python

by Jessica June 14, 2010

Interpolation
Interpolation is a used for many astronomical applications. Interpolation is required to combine sub-pixel dithered images or spectroscopy, sample grids of stellar evolution or stellar atmosphere models, calculate extinction from observed extinction curves, and many many more applications. The scipy.interpolate package in python has some nice built-in interpolation functions and I have gathered a few [...]

FITS images with catalog overlays

by Jessica March 17, 2010

I have been using ds9 to display images primarily due to inertia. I like the catalog tool for existing catalogs available online; but I wish there were a way to use custom catalog files without RA and Dec (just pixel coordinates) as well. I commonly resort to making ds9 region files, but this requires knowing [...]

Fourier Transforms of Images in Python

by Jessica March 3, 2010

There are many applications for taking fourier transforms of images (noise filtering, searching for small structures in diffuse galaxies, etc.). I wanted to point out some of the python capabilities that I have found useful in my particular application, which is to calculate the power spectrum of an image (for later separation of the distribution [...]
