astrometrilised

Astrometrilised is a term that has appeared in discussions and literature related to astrometry, the branch of astronomy concerned with the precise measurement of the positions and movements of celestial objects. While not a formally recognized scientific term with a widely accepted definition, "astrometrilised" is generally understood to describe the process of subjecting observational data to astrometric techniques or standards. This can involve applying rigorous methods for determining star positions, parallaxes, proper motions, and other kinematic parameters.

The application of astrometrilisation implies a move towards a higher level of precision and accuracy in astronomical measurements, often utilizing sophisticated instruments and data processing algorithms. For example, when astronomical surveys are "astrometrilised," it means that their raw observational data has been transformed into a catalog of precisely measured astrometric properties of the observed objects. This process is crucial for tasks such as constructing star catalogs, studying the structure and dynamics of the Milky Way galaxy, detecting exoplanets through their gravitational influence on stars (astrometric detection), and providing precise reference frames for other astronomical observations.

The concept of astrometrilisation is particularly relevant in the era of space-based astrometry missions like Hipparcos and Gaia. These missions have provided unprecedentedly accurate astrometric data for billions of stars, effectively astrometrilising large portions of the sky. The term, though informal, serves as a useful shorthand to convey the transformation of raw or less precise astronomical measurements into highly accurate astrometric data products.
