DS9 and Astropy

First we will learn a bit about the program “ds9”. It is an astronomical display program. After doing this setup you can run it by just typing ‘ds9’

You can play with ds9 a bit using this tutorial:

BTW that astrobites site is astronomy for undergrads written by graduate students. There is a lot of good articles there; start reading it! Or consider writing for it!

To start, do the tutorial and make a presentation explaining what you did for Friday group meeting. Try to follow the instructions in the ds9 tutorial and show us the steps to get to the last plots in your presentation. The links to the files (the FITS) files no longer work. But, you can go here to get them:

Then, here is a tutorial you can play with on FITS files. This will use ipython to look at data in an image. You should know how to start a iPython or Jupyter notebook from your physics classes already. If not ask one of the other LSST people.

Go ahead and do this. Some of the other astropy ones are good too.

• https://datacarpentry.org/astronomy-python/ - A good tutorial on database operations (SQL queries, joins, filtering) and to create publication-quality data visualizations

Play with these to get used to using the tools.
