Lecture 1
Useful Links:
Lecture 2
Useful Links:
- further information about the ICRS from the US Naval Observatory
- the International Earth Rotation Service (IERS)
- Earth Orientation information from the US Naval Observatory. For routines implementing the IAU 2000 model of precession and nutation, click on IERS Conventions 2003 and then on Chapter 5.
Lecture 3
Useful Links:
- a large collection of astronomical catalogs (including astrometric ones) can be found at VizieR
Lecture 4
Useful Links:
- JPL ephemeris for the calculation of precise positions of solar system objects at any give time (useful for calculation of parallax offsets). There is also an IDL program which can read and interpolate the JPL tables.
Lecture 5
Useful Links:
- The Recons Project
- The Catalog of Nearby Stars at CDS
- paper by Jahreiss & Wielen 2000: The Census of Nearby Stars Binaries at ADS
- two papers on details of refraction, if anybody actually needs to implement refraction corrections: paper by Monet et al. 1992 and paper by Stone 1996
- another paper on differential refraction: Gubler & Tytler 1998
Lecture 6
Useful Links:
- STEPS Project
- paper by Lindegren on atmospheric limitations in astrometry
- Hubble Space Telescope
Lecture 8
Useful Links:
- Documentation about the Hipparcos Catalogue, especially Vol.10, the Double and Multiple System Annex
