// This code is generated by generate_code.py, do not modify it manually.

//! This module contains all the known columns in the nss_vim_fl table.

use crate::traits::{Column, Table};

/// This table contains non-single-star models for sources compatible with an Variability Induced Mover (VIM) solution. Several possible models are in principle hosted within the same table and they are indicated by the field \texttt{nssSolutionType}. The description of this latter lists all possible solution types considered for this release. Only a selection of parameters hosted in this table are provided here, depending on the solution. The details of those is given in the description of field \texttt{bitIndex}, which can also be used to extract the relevant elements of the correlation vector \texttt{corrVec}. For DR3, only VIMF solutions are provided here. Details about the formalism used to derive the parameters in this table are given in the on-line documentation, see Chapter~\ref{chap:cu4nss}.
