Research Notes
- Theory of Photometry: A note discussing the underlying theory of photometry.
- Δ χ2 Values: A note discussing the origins of the numbers such as Δ χ2=2.3 is a 68% confidence interval for two degrees of freedom.
- Error Propagation: A note discussing how errors are propagated.
- Spectroscopy Basics: A talk for Hawai'i REU students given in 2009 on spectroscopy basics.
IDL Code
The programs require either the Spextool
package or cpar.pro, which can be found in the Spextool package (or just
comment out the cpar.pro call).
- mc_gridplotpos.pro: Used to create a grid of plots. Much easier to use than !p.multi.
- mc_filltable.pro: Used to write columns of data to a text file. Probably the most useful program that I have ever written!
- mc_loopprogress.pro: Gives an FTP-like progress bar on the terminal. If you have to use a FOR loop, then why not know where you are inside of it!
Figures
Please reference the original work if you use these figures in a talk.
If you would like something changed/added, drop me a line and I will see
what I can do.
