    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: The OrbFit Software Package (OrbFit Consortium - A. Milani et al, 2017) installed locally.
Note: OrbFit is unstable to run new multi-observations orbits, thus we accommodate two multi-step models.

NOTE: The output include many warnings, please scroll down for the results, while we will fix this inconvenient in the near future.


Current archive info:

Multi-step ephemeris model:  

Observations (in MPC format - example here):







Output style:


 
 

Fast (ephemerides computed relative to geocenter)
Slow (ephemerides computed relative to the observatory, only for intervals lower than 100 days)
