The method of astrometric measurements by Gaia is described from first principles, and the fundamental limitations explained in terms of physics (diffraction and photon noise), geometry, temporal sampling and reference frames.

Gaia measures the relative separations of the thousands of stars simultaneously present in the combined fields of view. The astrometric field in the focal plane is sampled by an array of 62 CCDs, each read out Gaia’s main astrometric instrument precisely determines the positions of stars in the sky. By combining the measurements of any given star over the five-year mission, it will be possible to determine its parallax (and therefore its distance) and its proper motion (the velocity of the star as it moves on the plane of the sky). Astrometric Instruments' Astrometric Telescope Control System (ATCS) : This PlugIn is meant to control telescope mount equipped with the ATCS controller (see the Astrometric Instruments Telescope Control Functionality).

Astrometric measurements are used by astrophysicists to constrain certain models in celestial mechanics. By measuring the velocities of pulsars, it is possible to put a limit on the asymmetry of supernova explosions. Also, astrometric results are used to determine the distribution of dark matter in the galaxy.

astrometric measurements, replaced in 1960's by more accurate VLBI and laser ranging techniques. For the Moon A 15 min CCD image was obtained for astrometric purposes on May 11, 1994, by Jean-Francois Claeskens at the Danish 1.5 m telescope at La Silla; it is here På 1500-talet använde Tycho Brahe förbättrade instrument, inklusive stora väggmålningsinstrument , för att mäta stjärnpositioner mer exakt än av RA Wittenmyer · 2007 · Citerat av 64 — 2006), and the High.

We identified several issues with the GPI data reduction pipeline (DRP) that significantly affected the determination of the angle of north So you're talking about the MaxDome II ( from Diffraction Limited )plugin not the DomePro2 (from Astrometric Instruments). You might want to open a dedicated thread for that (and I'll be more than happy to answer your question to the best of my abilities).
