They also make it possible to propose a synthesized model describing the interstellar extinction.Redundant 发表于 2025-3-24 05:28:20
Systematic Errors of High-Precision Photometric Cataloguesdes. The systematic errors are supposed to be bound up with the sky scanning procedure on the Hipparcos satellite. Polynomials in powers of coordinates have been proposed to take into account the systematic errors. 6558 stars have been found to be appropriate high-precision photometric standards.HAIL 发表于 2025-3-24 09:53:12

In this context, we describe one of the future developments of the BaSeL interactive web site to probe the GAIA photometric data: an automatic determination of atmospheric parameters from observed colours.Valves 发表于 2025-3-25 00:42:38
Japanese Astrometry Satellite Mission for Infrared Exploratione, JASMINE will also obtain photometry of stars in . and .-bands. The main objective of JASMINE is to study the most fundamental structure and evolution of the disk and the bulge components of the Milky Way Galaxy.
