    EURONEAR - Tools - Mega Precovery from Observations

Description: Precovery and recovery of new asteroids or comets from the Mega Archive (15 million images by Mar 2018).
Input: Astrometric observations of a new asteroid or comet (only one object, in MPC format).
Output: List of images probably showing serendipitous encounters of the object.
Using:
1. The FindOrb Software Package (Bill Gray - Project Pluto) installed locally. NEW!
2. The OrbFit Software Package (OrbFit Consortium - A. Milani et al, 2017) installed locally. (under maintenance) Instead, please use this mirror UCV tool.
- Note: OrbFit is unstable to run new multi-observations orbits, thus we accommodate two multi-step models.
