Comparison of Gaia BP/RP spectra with LDS (Low Dispersion Spectroscopy) photographic sky surveys
R. Hudec
Abstract:Blue (BP) and Red (RP) Photometer low-resolution spectral data is one of the exciting new products in the third data release of ESA satellite Gaia (Gaia DR3) 1 . The Gaia "photometric mode" RP/BP generates ultralow-dispersion prism spectra of celestial sources. The LDS (Low-Dispersion Spectroscopy) astrophysics was evolved and performed at numerous observatories (many in US) between ca 1909 and 1980. Mostly LDS with Schmidt telescopes was performed (plates with objective prism). These data were used in the pa… Show more
