OB Naming Conventions

General Rules

So as to facilitate the observers' job, some OB naming conventions have to be enforced. 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 ISAAC

Be aware of the naming conventions for the BURST/FastJitter mode OBs:

  • FastJitter OBs (BURST=F) should start with the prefix "FAST" in their name
  • Burst OBs (BURST=T) which do not make use of the EVENT keywords (EVENT.DATE=0 and EVENT.TIME=0) should start with the prefix "BURST" in their name
  • Burst OBs (BURST=T) which make use of the EVENT keywords (EVENT.DATE=YYMMDD and EVENT.TIME=HHMMSS) need to include the time at which the science template (not the acquisition!) should start, i.e. the UT time of the EVENT time minus half the total exposure time. For example, let's assume that you are exposing for 30 sec in total and let's assume that your event occurs at UT date YYMMDD and UT time HHMMSS, then, your OB name should include the following prefix: "BURSTUTYYMMDDHHMMss", where ss=SS-30/2=SS-15.
