Science Tools Working Group

Did not meet this week. We won't meet until after the collaboration meeting.

The current version of ScienceTools is v8.

Likelihood analysis

  • Handling of comparisons with DSS keyword values and values in binary tables of FITS files has been fixed; see LK-31. (Likelihood v11r14p2)
  • Added Damien Parent's PowerLawSuperExpCutoff as a spectral model available in gtlikelihood and pyLikelihood. This spectral model is needed for modeling pulsar spectra (in the Polar cap scenario). (Likelihood v11r15; pyLikelihood v0r6)

GRB tools

  • gtrspgen: problems with integrals of energy dispersion over large energy ranges for handoff_response and dc2Response have been addressed in irfInterface::IEdisp. (irfs/irfInterface v2r1; irfs/dc2Response v3r1)

Pulsar tools

  • Masa and James have finished coding the blind search tool gtspec. Testing on DC2 data is underway.

Observation simulation

  • From Max Razzano:
    • "EGRET phase-dependent sources, fixes and extended down to 10 MeV. The lightcurve have been smoothed for the 3 faintest (no phase-dependence) and for Vela, Crab and Geminga we have phase dependent spetcrum and also some very narrow features that we can use for testing timing resolution;
    • "Timing noise on 5 pulsars, based on Cordes algorithm of Random Walk(in phase) and of Arzoumanian (f2 based on Delta8 parameter);
    • "3 MSP in binary orbits, we have this last problem but I solved and it is ok;"

User interface and infrastructure (& utilities)

  • Pat and Jim added a new C++ implementation of dgaus8 (translated from Java, which was translated from the original spaghetti Fortran) to replace the f2c'd version. (st_facilities v0r10p1)
