RGB photometric calibration of 15 million Gaia stars
Nicolás Cardiel, Jaime Zamorano, Josep Manel Carrasco +6
Although a catalogue of synthetic RGB magnitudes, providing photometric data for a sample of 1346 bright stars, has been recently published, its usefulness is still limited due to…
Internal calibration of Gaia BP/RP low-resolution spectra
J. M. Carrasco, M. Weiler, C. Jordi +6
The full third Gaia data release will provide the calibrated spectra obtained with the blue and red Gaia slit-less spectrophotometers. The main challenge when facing Gaia spectral…
Gaia Photometric Science Alerts
S. T. Hodgkin, D. L. Harrison, E. Breedt +108
Since July 2014, the Gaia mission has been engaged in a high-spatial-resolution, time-resolved, precise, accurate astrometric, and photometric survey of the entire sky. Aims: We pr…
A multi-band map of the natural night sky brightness including Gaia and Hipparcos integrated starlight
Eduard Masana, Josep Manel Carrasco, Salvador Bará +1
The natural night sky brightness is a relevant input for monitoring the light pollution evolution at observatory sites, by subtracting it from the overall sky brightness determined…
Gaia Early Data Release 3: Photometric content and validation
M. Riello, F. De Angeli, D. W. Evans +39
Gaia Early Data Release 3 contains astrometry and photometry results for about 1.8 billion sources based on observations collected by the ESA Gaia satellite during the first 34 mon…
Spectrophotometric calibration of low-resolution spectra
Michael Weiler, Josep Manel Carrasco, Claus Fabricius +1
Low-resolution spectroscopy is a frequently used technique. Aperture prism spectroscopy in particular is an important tool for large-scale survey observations. The ongoing ESA spac…
J-PLUS: photometric calibration of large area multi-filter surveys with stellar and white dwarf loci
C. López-Sanjuan, J. Varela, D. Cristóbal-Hornillos +22
We present the photometric calibration of the twelve optical passbands observed by the Javalambre Photometric Local Universe Survey (J-PLUS). The proposed calibration method has fo…
Gaia Data Release 2. Short-timescale variability processing and analysis
