Salut,
Le sujet est ancien mais toujours d'actualité. Je ne me souviens pas t'avoir répondu. Voici un exemple de paquet de données généré par un autre code qui a été envoyé et accepté par le MPC :
# version=2017
# observatory
! mpcCode A77
# submitter
! name
# observers
! name M. Serrau
# measurers
! name M. Serrau
# telescope
! design 0.275-m f/7.3 reflector + CCD
! aperture 0.0
! detector CCD
# software
! astrometry Astrometrica 4.12.0.448
! photometry Astrometrica 4.12.0.448

Il y une seule mesure (sur la dernière ligne qui commence par 2P|). Cet exemple est ancien et il n'est pas sûr que le MPC n'ait pas implémenté de nouvelles règles sur ce type de données qui rendent mon exemple caduque. Pour preuve un message de Bill Gray lu sur la liste mpml en réponse à D. Parrot au sujet des tracklets (trkSub) :
Hi Daniel
That PDF is dated in 2015 and is the 'proposal' for
ADES. The current version is in two PDFs found at
https://github.com/IAU-ADES/ADES-Master/
along with various examples of ADES, source code, and
other bits and bobs. ADES_Description.pdf appears to be the
current version of IAU2015_ADES.pdf. The relevant part still
starts on page 10, but has been rearranged quite a bit.
As you say, the older documentation says that for targeted
follow-up observations, provID "could be an NEOCP temporary
designation". That's gone from the current documentation.
provID is described as containing an "MPC provisional
designation (in unpacked form) for unnumbered objects." Page
11 of the current docs lists assorted permissible permIDs and
provIDs. Neither includes observer-supplied temporary desigs.
On the table shown on page 10 of the current documentation,
there are four alternatives A through D. It looks to me as
if the only place you can report an NEOCP (or, more generally,
an observer-specified) designation is in trkSub. So for any
submission for an undesignated object, your only alternative
is option D: you set the trkSub and omit everything else.
There is a small discrepancy here, though. Page 10 says
that "for targeted follow up with more than one tracklet of
the same object in the submission, the trkSub field should
be used to distinguish the individual tracklets." If you
observe NEOCP object XYZ on two separate occasions, resulting
in two tracklets, it appears to me that you can't submit them
in one batch. You submit the first tracklet, with trkSub
set to XYZ. Then submit the second tracklet separately, again
with trkSub XYZ.
I'll ask around a bit. Maybe I'm missing something.
