Lately I've been doing a lot (millions) of calculations involving small NumPy arrays of HST PSFs. Naturally, I wanted to save the output of these calculations to for later analysis. I put all the results in a MySQL database so I could easily select subsets of the data for ...

Update 01/30/2014: Adam has split his gaussfitter code off into it's own GitHub repository here ("PR's Welcome!"). This removes some dependencies and changes the import statement but as of right now everything else is the same. I've maintained the old links to the original agpy ...

Ran the full pipeline the PSF data for the first time. The data are inconclusive.

Haha, oh error bars. Who hasn't made a plot ...

In my last post on my PSF Project I characterized the PSF shape by fitting a 1-D Gaussian to the a row and column slice through the central pixel. In this post I start to think about how to characterize entire images with thousands of stars.

Adding Some Zeros

Many ...

I've started a new project working with 10 million stellar PSFs. In my first few steps in the project I performed some model fitting and made a pretty visualization of the individual data points.

My New (Little) Big Data Project

I am starting a new project that I'm ...
