Explore a detailed record of stellar parallax from the late 19th and early 20th century, presented with careful measurements and transparent methods.
This edition compiles the observational work of Albert Stowell Flint, focusing on how parallax was measured, reduced, and compared with other large series from observatories around the world. It covers star selection, telescope setup, and the procedures used to extract precise timing and position data from transit observations. The volume includes explanations of the instruments, screens and slat devices used to adjust brightness, and the mathematical steps used to derive relative parallaxes from the collected observations.
- Learn how stars were chosen for a parallax program and how comparison stars were paired for accurate results.
- See the hardware and techniques behind meridian circle observations, including screen reduction and micrometer usage.
- Understand the data presentation, including the structure of tables, the meaning of columns, and how normal equations lead to adopted parallax values.
- Read notes on reconstruction of results and how they were checked against other major studies.
Ideal for readers of historical astronomy, data-focused researchers, and anyone exploring the evolution of stellar parallax methods.
