Provisional designations - Participation of station Z40

The table contains all provisional designations from the corrected (alls IDs from dbl.txt and ids.txt are used) dataset UNNOBS of the Minor planet Center, for which the station Z40 has made additional observations, but not the discovery itself or got a discovery star.

Explanations:
Nr: Running number.
Designation: Long designation of the object.
Short: Packed designation of the object.
Obs start: First date for this designation (may be not the first date for object due to prediscovery identifications).
Obs end: Last date for this designation (may be not the last date for object due to later identifications).
Int: Difference between last and first date in days.
Z40 start: First date of Z40 for this object.
Z40 end: Last date of Z40 for this object.
Int: Difference between last and first date of Z40 for this object in days.
Discovery: Date of discovery for this designation.
Sta: Discovery station.
Obs: Number of observations for this object.
Own: Number of own observations for this object.
Sta: Number of stations for this object.
Opp: Number of observed oppositions for this object.
Stars: Stations with discovery stars in all observations of this object. The 'real' discovery station is mostly the first one. Sometimes you must check the details of publication date and the sending date (which you may know, when you sent the data).

A 'missed' at end of line means, that this stations has made only one single-night observations in one opposition (and no other station has do another observations in this opposition) before the discovery. So it fails, because another second night is missing.
