EURONEAR - OBSERVING TOOLS: ARCHIVE PRECOVERY AND RECOVERY
Please acknowledge the following paper if you use this server: Vaduvescu et al. 2009 AN 330, 698
This program searches for all known asteroids imaged serendipitiously in an archive of images or photographic plates. To perform the actual search, the program is querying the SKYBOT server developed by J. Berthier et al. at IMCCE using the entries from the observing log archive.
Both "precoveries" (apparitions before discovery date) and "recoveries" (apparitions after discovery date) are reported by comparing the observing dates with the discovery dates kept in a local database. The following classes of asteroids are reported: PHAs (Potentially Hazardous Asteroids), NEAs (Near Earth Asteroids), Numbered (cataloged), and Un-numbered (having temporary designations).
Output data: 7 ASCII files listing all apparitions (to be downloaded by the user).
Caution: due to the very high number of known asteroids to date which need to be integrated numerically (almost 500.000 orbits), the response from the SKYBOT server takes as high as a few minutes to search for every entry of the observing log file. Thus, the search of the entire archive might take as much as a few hours or a few days to perform, so please be cautious with the number of entries! Splitting the observing log in a few smaller files (e.g. up to 250 entries) and launching parallel queries might be an option.
The script accepts observing log archives in three formats:
1. Observing logs from CFHTLS (Canada-France-Hawaii Legacy Survey):
2. Observing logs in a standard format including the following fields: image id, Julian Date (obs start), exp time (sec), RA image center (hrs with decimals), DEC image center (degrees with decimals), image field in RA (deg), image field in DEC (deg), comment - all fields separated by the pipeline "|" character:
3. Observing logs from INT WFC (Isaac Newton Telescope, ING) in a standard format (same as above):
4. Observing logs from ESO/MPG WFI (ESO/MPG) in a standard format (same as above):
5. Observing logs from SUBARU Suprime-Cam (SUBARU Suprime-Cam) in a standard format (same as above):
