Individual, Single Starsrtant for their scientific exploitation. The problem is, that although precisions can be determined quite easily, accuracies are much harder to obtain. In general, errors can originate from two sources: internal (photon statistics, random noise introduced in instrument modelling), and external error

The Astrometric Data for Composite Images and Orbital Binariesd been included in the . Input Catalogue for their astrophysical importance: a resolved double star system with well determined orbital parameters and an accurate parallax provides direct measurements of stellar masses, and in case the system also shows eclipses, stellar radii. The processing of . d

Groups of Single Starsents of individual stars alone. This is made possible primarily by exploiting parameters common to groups of stars, such as parallax and proper motion for members of a star cluster, or period-luminosity relations for groups of pulsating stars. In this chapter techniques used to extract such paramete

A Free-Floating Rigid Body in Spacenslations are described by the orbital dynamics (Section 1.2.3), the rotations are covered by the attitude description. Understanding the rotations from a theoretical point of view is the main topic of this Chapter, which presents the theoretical background for describing the rotations of a rigid bo

The Torques on Hipparcos As Observed Over the Missiong of the error angles, as was done for the published data (Chapter 10). However, this process could only be started from a preliminary reconstruction of torques as based on the old, published solutions. From the old attitude solutions the underlying torques, as well as the inertia tensor characteris

Payload Calibrationsegular basis by the so-called First-Look processing (see for example Schrijver and van der Marel 1992), and also as part of the NDAC and FAST full-scale data reductions. Also after completing all reductions useful information can be extracted from the calibration data. When compared with the spacecr
