17.1 Catalogue statistics

17.1.5 Radial velocity spectra (RVS)

rvs_mean_spectrum table

The data fields of rvs_mean_spectrum are described in Section 20.12.1. Statistics are provided in Table 17.18 and a selection of plots in Section 17.2.9.

Table 17.18: rvs_mean_spectrum. Statistics for the 999 645 sources. Arrays in a data record are represented by their average (.avg), length (.len), maximum (.max), median (.med), minimum (.min) and the number of NaN elements (.nan), and the statistics are formed over these values.
