mean sampled Radial Velocity Spectrometer (RVS) Spectra (gaiadr3.rvs_mean_spectrum)

The table has 999645 rows, 9 columns.

Description

This is the RVS mean sampled spectrum table. The spectra are in the rest frame, they are normalised and their wavelength grid ranges from 846 to 870 nm in steps of 0.01 nm (2401 elements). See  Section cu6spe_meanspe for a description on how the mean spectra are obtained, and  DR3-DPACP-154 for a description of the spectra validation.
