DMS-REQ-0392-V-01: Alert Delay and Failure Tolerances_1

    Details

    • Type: Verification
    • Status: Not Covered
    • Priority: Undefined
    • Resolution: Unresolved

    • Requirement ID:
      DMS-REQ-0392
    • Requirement Text:

      Specification: The system shall reliably produce alerts for standard science visits read out in the camera [and specified to be analyzed by Data Management] such that no more than sciVisitAlertDelay per cent of visits will fail to have at least OTR1 per cent of its alerts distributed via the LSST alert distribution system within OTT1, and no more than sciVisitAlertFailure per cent of visits will fail to generate and distribute alerts (integrated over all stages of data handling)

    • Requirement Parameters:

      [OTR1 = 98[percent] Fraction of detectable alerts for which an alert is actually transmitted within latency OTT1 (see LSR-REQ-0101)., sciVisitAlertFailure = 0.1[percent] Maximum fraction of visits for which alerts are not generated or distributed., OTT1 = 1[minute] The latency of reporting optical transients following the completion of readout of the last image of a visit, nAlertVisitPeak = 40000[integer] The instantaneous peak number of alerts per standard visit., sciVisitAlertDelay = 1[percent] Maximum fraction of science visits with less than OTR1 percent of the alerts distributed within OTT1.]

    • Requirement Discussion:

      Discussion: As with DMS-REQ-0004, this specification applies to visits which should have resulted in fewer than nAlertVisitPeak.

    • Higher Level Requirement:

      OSS-REQ-0112: 01 Science Visit Alert Generation Reliability
