- 25 April 2018
Context. The second data release of the Gaia mission (DR2) includes an advance catalogue of variable stars. The classifications of these stars are based on sparse photometry from the first 22 months…
LSST: From Science Drivers to Reference Design and Anticipated Data Products
- vZeljko Ivezi'c, S. Kahn, for the Lsst Collaboration
- PhysicsAstrophysical Journal
- 15 May 2008
The LSST design is driven by four main science themes: probing dark energy and dark matter, taking an inventory of the solar system, exploring the transient optical sky, and mapping the Milky Way.
Gaia Data Release 2
- F. Spoto, P. Tanga, T. Zwitter
- PhysicsAstronomy & Astrophysics
- 25 April 2018
The dramatic improvement brought by Gaia DR2 astrometry of SSOs is demonstrated by comparisons to the archive data and by preliminary tests on the detection of subtle non-gravitational effects.

A comprehensive overview of the mathematical and physical models applicable to the astrometric core solution of the Gaia satellite, using a global solution approach, as well as its numerical and algorithmic framework is provided.
Preparing Red‐Green‐Blue Images from CCD Data
- R. Lupton, M. Blanton, N. Wherry
- Physics
- 18 December 2003
We present a new, and we believe arguably correct, algorithm for producing red‐green‐blue (RGB) composites from three‐band astronomical images. Our method ensures that an object with a specified…
