Reason for Change

There is a bug in ScienceTools v9r4p2 (in Likelihood v13r12p1 and earlier) for which very short time intervals of data (less than 1 sec) are not handled correctly in the livetime calculation. This bug was uncovered in the analysis of a sub 1 second burst during OpsSim2.

ST v9r5 also has a new version of gttsmap (Likelihood v13r14) that allows for more general projections on the sky. This will be useful for plotting error contours for bursts at high Celestial or Galactic latitudes.

Test Procedure

The fix version, Likelihood v13r13, and current release version, Likelihood v13r14 now in ST v9r5, have passed the ST unit and system tests. ASP has been run on a standard test dataset in /ASP/TestSims in the dev datacatalog; it has also been run on the OpsSim 2 data to verify that the short-time scale GRB is handled correctly.

Roll-back Procedure

Reset the ST_INST pipeline stream arguments to point to the v9r4p2 build. Reset the ST_INST environmnent variable to point to v9r4p2 and rebuild the ASP package in the prod area.

Details

Various code changes are required in ASP:

  • grbASP/python/refinePosition.py: use new gttsmap pfile parameters
  • pgwave/python/getPgwDataInputData.py: use new gtselect pfile parameters
  • drpMonitoring/python/fitEnergyBand.py: use pyLikelihood/python/UpperLimits.py instead of local implementation
