Part 1 was a 2-liner with astropy.ascii.read() - all ready for Table manipulation. Part 2 needed a bit of counting spaces, but went well (unlike part 2 of yesterday, which I haven't solved).

Today we signed an agreement with an international consortium for the design and construction of the ELT instrument MOSAIC.
MOSAIC will help trace the growth of galaxies and matter distribution from the Big Bang to the present day.

Our Unit Telescopes combine their light with interferometry to obtain the level of detail of a huge 130 m virtual telescope. But this requires correcting the effects of Earth’s atmosphere. This is where the lasers come in.

Interesting paper. The authors originally wanted to see how they could recover bar properties from simulations. It turned out that gender mattered most, followed by career stage. Females find small and early bars, males find large bars. Make of that what you will. 🤣

Today, thanks to the folks at e-science at @aippotsdam.bsky.social, we started "vibe coding" (AI/LLM with cline + Claude / OLLAMA). It's fine and it does make a lot of work faster, makes beautiful plots. But it requires so... much... describing. Exactly what I hate.
