sso_observation table

The data fields of sso_observation are described in Section 20.11.2 and statistics are provided in Table 17.21.

Table 17.21: sso_observation. Statistics for the 23 336 467 observations. 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.
