OB Naming Conventions
So as to facilitate the observers' job, some OB naming conventions are required. Regardless of the instrument, the following generic prefixes must be used when naming OBs:
- PRE_ - pre-imaging OB (e.g. PRE_Field A)
- TOO_ - Target of Opportunity OB (e.g. TOO_GRB-1); see also note below
- RRM_ - Rapid Response Mode OB (e.g. RRM_grb346+580_3x600s)
- MOV_ - Moving Target (i.e. solar system) OB (e.g. MOV_TNO-43A)
- CAL_ - Calibration star (e.g. photometric, telluric, radial velocity, polarization, etc) (e.g. CAL_TNO-43A)
Note: All observations belonging to a ToO run must start with the TOO_ prefix, including those belonging to the other categories mentioned above: for instance, an OB intended to observe a star for calibration of a ToO science observation should have a name starting with TOO_CAL_.
Note: Pre-imaging OBs for moving targets should have a name starting with the prefix MOV_PRE_.
For OB time sequences, please name your OBs in such a way that the sequence is obvious. Examples:
Field A - Night1
Field A - Night2
Field A - Night3
Field B - Baseline
Field B - Baseline + 1 week
Field B - Baseline + 2 weeks
Please use always a unique name for each of your OBs, even if they are identical to each other. For example, a series of 3 identical OBs on NGC 5128 may be called NGC5128-1, NGC5128-2, NGC5128-3, instead of calling all three OBs NGC5128.
Please use always names which do not contain 'No Name'.
Note: allowed characters in the OB name: letters, digits, space, + - _ .
Additional naming rules for NACO
- For PSF reference stars the OB name must be prefixed with the string:
- PSF_ for normal observations
- PRE_PSF_ for pre-imaging observations
- TOO_PSF_ for Target of Opportunity (ToO) observations.
- For observations that require tracking the target (as nearly as possible) symmetrically with respect to the meridian (e.g. ADI observations) users are asked to include as a suffix to the OB name the string _MERIDIAN. Please see the NACO Service Mode Rules page for additional details regarding OBs that should track through the meridian.
