ObsBlock without start or stop time

AGM supports observation block with missing start or stop time. They are interpreted as flexible blocks that will be resolved by AGM.

  1. At the moment, these PTR will be considered by the read_ptr() as invalid because the ObsBlock enforces a start and a stop time to support blocks overlap and sorting checks.

Workaround: additional development is required to accommodate this type of scenario but the user can bypass the read_ptr() and submit directly its PTR to AGM with agm_simulation().

  1. AGM resolved PTR is currently no distributed by the JUICE pointing tool but an implementation is planned. When available it should be possible to retrieve it from the AGM simulation results (similarly to the generated ck file).

Open question:

  • Is is possible to have a PTR with both start and stop time missing ?
