OBSOLETE
The “Asteroid & Comet Field-of-View Search Request” (ispy/fov) tool
https://ssd.jpl.nasa.gov/x/fov.html
is obsolete.
It has been replaced by
If needed, the prior “ispy/fov” system, with its additional uncertainty mapping and other options,
can still be accessed by sending e-mail command files with the subject “FOV”
to horizons@ssd.jpl.nasa.gov
,
as documented.
Eventually, parallelized “ispy/fov” functionality and output will return in the new tool and API interfaces, but that development is pending, so only e-mail command-file access for that right now.
