Science & Technologynon-Single stars Tools
To be able to easily handle the non-single star (NSS) solutions provided for the first time inGaia DR3, two functionalities have been developed to:
- convert the correlation matrix and uncertaintes into thecovariance matrix of the NSS solutions without bothering with the matrix indices;
- convert the Thiele-Innes orbital elements of the astrometric solutions to theCampbell elements with uncertainties propagation.
The tool is available both in Python and in R:

Credits: The NSS Tools have been developed by N. Leclerc and C. Babusiaux, based on a software code from J.-L. Halbwachs.
