报告摘要:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Astrometry of NEOs, and of small solar system objects in general, is essential to ensure that new discoveries are sufficiently characterized and do not become lost. Knowing the orbit and the ephemeris of an object with sufficient precision is key to obtain other observations, and at the same time it allows us to understand the future dynamics of the object and, in the case of NEOs, predict future close approaches or impacts.
How to go from images to astrometric observations:
- Data (non)-processing
- Astrometric reduction and software
- Stacking
- Checking the quality of the observations, orbit fit
- Submission to the Minor Planet Center
