Here’s a performance comparison for FFT-based correlation of a 1,000,000-sample dataset, using your original reference system (i5-6500, 8GB) and several upgraded configurations, including newer 12th-gen Intel CPUs. ⚙️ Test Overview…
Here’s a standalone Python script you can run on your Linux system later. It generates two synthetic signals, performs FFT-based correlation, and saves the result to a timestamped .npy file…
The Intel i5-8500 with 16GB RAM will be noticeably faster than the i5-6500 with 8GB RAM for processing radio astronomy data, but the actual performance gain depends on the nature…
No, astro-all is not a valid package in Ubuntu by default. If you run: You’ll likely get an error like: Alternatives to astro-all If you’re looking to install a comprehensive…
In Debian and its derivatives (like Ubuntu, Raspbian, etc.), there’s no official meta-package specifically for radio astronomy. However, you can create a custom meta-package to install a set of radio…
April 2026: The following is my attempt to work out logic for achieving a successful interferometry experiment. I use this blog as my lab notes, so some of the entries…
To use RSPUno for interferometry, you’ll need to understand both the hardware configuration and the software/data processing workflow. RSPUno is a system derived from the Radio-SkyPipe software but optimized for…
