nss_acceleration_astro table

The data fields of nss_acceleration_astro are described in Section 20.6.2. Statistics are provided in Table 17.14 and a selection of plots in Section 17.2.13.

Table 17.14: nss_acceleration_astro. Statistics for numeric fields for the 338 215 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.
