Argon 从 Event Horizon Telescope 档案中提取 230 GHz 射电干涉原始数据（UVFITS），用 3 天线闭合相位构建干涉测量求解器以消除大气噪声，每次运行均从无环形模板或掩膜的纯高斯斑块起步，复现了 M87*（2017 与 2018）和 Sgr A*，与官方 EHT 图像匹配度达 91% 至 98%。

I've been doing some hobbyist astronomy with Argon. Here's one of my experiments, where I tasked Argon with reproducing the first black hole images (from 2017/18) using the same raw data.
Argon:
- pulled raw 230 GHz radio fringes (UVFITS) from the Event Horizon Telescope archives.
- built an interferometry solver using 3-dish closure phases to cancel atmospheric noise
- started each run from a plain Gaussian blob with no ring templates or masks
- recovered M87* (2017 & 2018) and Sgr A* at a 91% to 98% match of the official EHT images
