VizieR Online Data Catalog: DIBs in Gaia DR3 RVS spectra (Zhao+, 2024)
Abstract
We developed a Random Forest model to isolate the DIB features from the stellar components and applied this method to 780 thousand spectra collected by the Gaia Radial Velocity Spectrometer (RVS) that were published in the third data release (DR3). After subtracting the stellar components, we modeled the DIB at 862.1nm with a Gaussian function and the DIB around 864.8nm with a Lorentzian function. After quality control, we selected 7619 reliable DIB measurements. Their fitted DIB parameters, as well as the parameters related to the background stars and spectra, are released in this file.
