Yearly Breakdown of MPEC Types

Term definition:
Editorial - Editorial MPECs associated with this station.
Discovery - MPECs associated with discovery made by this station.
OrbitUpdate - MPECs associated with orbit updates involving observations made by this station. Typically, these are recoveries of single-opposition objects.
DOU - Daily Orbit Update MPECs involving observations made by this station.
ListUpdate - MPECs associated with list updates involving observations made by this station. This category has largely been retired since 2012.
Retraction - Retracted MPECs involving observations made by this station.
Followup - MPECs associated with follow-up observations made by this station to an object discovered elsewhere.
FirstFollowup - MPECs associated with follow-up observations made by this station to an object discovered elsewhere, with this station being the first station to follow-up.
Other - MPECs that do not fit into categories listed above and involve observations made by this station.
