Observation Status Codes

The following status codes are used in our internal database of observations. Observations with any of the first three codes, "P", "p", or "I" are available in replicated copies of our database. Observations with any of the other codes are not public. A list of observations removed from circulation since the most recent Circular is published daily in conjunction with the Daily Orbit Update (DOU).

Note: asterisks that appear in any observations are as originally submitted and are not an indication of discovery credits.

P - Published
p - publication pending (e.g. in MPEC for NEA, or next MPS for MBA)
I - Isolated tracklet file (ITF)

X - unprocessed
D - Deleted
R - Rejected
M - unused near-duplicate observation
U - Unidentified isolated observation
? - unknown status (only for very old data)
