This flag is in use for several system's in the down-link and up-link
part of ISO. For example the off line processing group and the data
distribution system reads ID_OBS. Further it is important for the
mission planer, and so for the scheduling of your observations.
The ID_OBS must uniquely identify each individual measurement and must
identify the proposal ID and observation ID. The ID_OBS has a number
of 10 fields for numerical and upper case alphabetic symbols. The last
two field names must be `_A', so that 8 symbols are still free.
Please use one of the fields no 6, 7 and 8 to enter a unique number
for your measurement. For example measurement no. 13 should read
`013'. However, this number does not indicate that there is a kind of
order in the time sequence of your observations. Observation with an
assigned number `001' can of course be scheduled months later than
observations with a number `008' in the ID_OBS fields 6-8:.
The remaining fields shall be used to uniquely identify the proposer
and observer ID. Those fields should be in upper-case alphabetic order
and can be the first letters of your observer ID. For example
Mr. Smith with obs_id MSMITH should enter for his measurement
identified as `011':
ID_OBS = MSMIA011_A
In case you have more than one proposal you may specify: `JHOUGA' and
`JHOUGB'.
We understand that this must read quite confusingly so let us try to
give another 2 examples. Let us take again Mr Smith having 2 proposals
with PROP_ID : `MSMITH_YSO' and `MSMITH_AGN', for his proposal on
young stellar objects and active galactic nuclei. Observer Smith
could use for his observation no.: 10 in YSO for example:
ID_OBS = MSMIY010_A
and for his observation no.11 in his AGN proposal
ID_OBS = MSMIA911_A
