HETE-2 Mission Status:

HETE-2 Mission Status: Instruments (FREGATE, WXM & SXC): nominal operations (WXM 2-D localizations reduced by ~20% after failure of YB module) localization of 25 bursts since last HUG meeting GRB030329 (HETE-2 burst H2652): “missing link burst” (GRB/SN connection). Last HUG meeting:

Presentation Transcript

  1. HETE-2 Mission Status: • Instruments (FREGATE, WXM & SXC): nominal operations (WXM 2-D localizations reduced by ~20% after failure of YB module) • localization of 25 bursts since last HUG meeting • GRB030329 (HETE-2 burst H2652): “missing link burst” (GRB/SN connection)

  2. Last HUG meeting: The HUG noted that there has been little progress making HETE data products available in standard FITS format accessible using software familiar to the community. For GRBS, multicolor lightcurves are available in FITS, and this is probably sufficient. However, for the coded mask data, potentially useful for monitoring bright Galactic sources, there is no standard format or documented software. The HUG appreciates that the HETE2 team has no funding to support such development activities, and the HEASARC does not have personnel to dedicate to the task. If the HETE2 team and HEASARC cannot get additional funding for this task, the HUG urges the HEASARC to consider some intermediate solution where processed lightcurves and/or spectra for selected sources could be archived in FITS.

  3. Developments since last HUG • IPP archive at HEASARC current through Feb 04 • Proprietary restrictions are removed - data immediately public • Tools to split out Science data from telemetry (non FITS) for all instruments • continued FITS conversion of HETE GRB lightcurves • new BROWSE table: HETEGRB • allows access to HETE-2 GRB lightcurves from BROWSE • links directly from table entries to MIT HETE page for each burst)

  4. MIT Developments since last HUG: • ASCII multicolor lightcurves for FREGATE A (7-40 keV), B (7-80 keV), C (30-400 keV) bands • color-color plots of FREGATE data (C/A vs. B/A) for source ids • cutoff power-law spectral fits for high s/n FREGATE burst spectra • plus skymaps

  5. (Still) In Progress: • Production of WXM standard products for archive, including • documentation of processing steps • definition of FITS formats (coordinate w/ SWIFT, INTEGRAL where applicable) • creation of FITS lightcurves and spectra • Incorporation of standard FREGATE spectra and responses for all bursts • Incorporate SXC data

  6. Data Flow
