5.6. Producing Quasi-Definitive Data

The production of quasi-definitive data is generally similar to the process described here for definitive data, the difference being that quasi-definitive data should be sent within 3 months after their acquisition. Quasi-definitive data are produced using the best available baselines at the time of production, providing these data meet the quality specification of quasi-definitive data as given in APPENDIX A. Observatories are likely to adopt the same process to produce quasi-definitive data as they do for definitive data as this simplifies the production of definitive data at the end of the year. Example methods of quasi-definitive production adopted by some institutes are listed in Section 6.3.5.
