NOTES              
(a) Amalgamation with other observation(s). No dedicated exposure time required.    
(b) PI's are being informed on TAC comments and constraints (incl. data rights) concerning their observation.    

 

Notes on scientific grade

The INTEGRAL TAC approved individual observations of a proposal by assigning a grade, A, B, C or TOO (for Target of Opportunity observations) to each observation.  A special sub-group of proposals, using serendipituous data on GRB's, has been identified as GRB.

The characteristics of a specific grade are as follows:
 

  • A: Excellent proposal. Highest scheduling priority. A-grade proposals which can not be scheduled during AO-1 will automatically be carried-over to AO-2, i.e. no re-submission to TAC for AO-2 is required. This does not hold, however, for TOO observations (see below), which must be re-proposed for AO-2 in case they are not scheduled during AO-1.
  • B: Very good proposal. High scheduling priority. B-grade proposals which can not be scheduled during AO-1, must be re-submitted for AO-2 when B-grade targets become free for new proposals.
  • C: Good proposal. Low scheduling priority. C- grade proposals which can not be scheduled during AO-1, must be re-submitted for AO-2 when C-grade targets become free for new proposals.
  • TOO: Accepted TOO proposals have always grade A for scheduling priority. See above for further details. TOO observations will only be executed if certain trigger criteria are fulfilled. The maximum time to be spent and source constraints are given above. TOO proposals will, unlike other grade A proposals, not be transferred to AO-2, but must be re-submitted for AO-2.
  • GRB: No scheduling impact as serendipituous data are being used.


    • General note on scheduling: The scheduling on INTEGRAL will be optimized in such a way that greatest scientific return is ensured within the
    time available. Consequently the allocated priorities do not  reflect the sequence of the observation within the AO-1 cycle. However, it is emphasised that - for operational and technical reasons- no guarantee can be given that any particular observation will in fact be executed.


    The Core Programme (guaranteed time) observations, which complete the INTEGRAL observing programme, can be found here.
