5.6. Producing Quasi-Definitive Data

The production of quasi-definitive data is similar to the process for definitive data, the difference being that quasi-definitive data are submitted within 3 months of acquisition. Provided quasi-definitive data are produced using the best available baselines such that data meet the specification given in APPENDIX A, any method can be used. Observatories typically 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. Examples of processes used by some institutes are listed in Section 6.3.5.
