Sampled BP/RP mean spectrum (gaiadr3.xp_sampled_mean_spectrum)

The table has 34468373 rows, 6 columns.


This is the BP/RP externally calibrated sampled mean spectrum. All mean spectra are sampled to the same set of absolute wavelength positions, which can be found in the field wavelength of table XpMerge.
