    My software development is tracked on github.

    HERA Software

    Much of my recent activity has been within the HERA-Team project, which is the home of all the code for the HERA telescope. Specifically, I manage the data quality metrics repository, hera_qm, and am a core contributor to pyuvdata, a python model for interferometric data.

    Other Software

    The EPIC-Astronomy github team contains all the EPIC codes and memos.

    I have made major contributions to the Fast Holographic Deconvolution (FHD) and eppsilon code bases, which are essential tools for the imaging power spectrum pipeline I used in my PhD thesis.

    I have been populating a tutorial repository with jupyter notebooks and python scripts that I use to demonstrate concepts when teaching. Check out the Photo_FT_animation.py script!

    HERA Memos

    The full HERA memo series is hosted on reionization.org. Below are my contributions.

    An early look at HERA-19 system temperature (Beardsley)

    Modeling Sky Temperature (Parsons and Beardsley)

    System Temperatures of 21 cm Arrays (Jacobs, Beardsley, Hazelton, Thyagarajan, Trott)

    Other Memos

    Below are a handful of memos I have prepared for various groups. Some have found them useful, so I post them here for easy access. The scope of some memos evolved while writing, but I don’t want to change the titles in case people have referenced them. Instead I added notes on the content for ones that are not obvious from the title.

    These are meant to be instructional, but not comprehensive. I do not claim completeness, and errors are possible. If you find an error, or need clarification, feel free to contact me.
