HETE-2: Asmall satellite designed to detect and localize gamma-ray bursts • Instruments: • FREGATE (6-400 keV) • Wide-field X-ray Monitor (WXM) (2-25 keV), localization accuracy to ~10 arc-minutes or better. • The soft X-ray camera (SXC) (0.5-10 keV) localization accuracy to 30 arc-seconds or better. • Launched: Oct 9 2000 • Operations: MIT/CSR • Archive: HEASARC
HETE-2 Highlights • 25 confirmed GRBs; optical transient (D. Fox, Caltech); “Dark Burst” • Uptime of groundstations improved • Attitude control system change to point away from bright contaminating sources (Sco X-1, Galactic Center, moon) • New flight algorithms for SXC implemented to compensate for loss of optical blocking filters, increase SXC ontime • Senior Review: fund HETE-2 til launch of Swift, then terminate
The HETE-2 Archive at the HEASARC: • Opened: February, 2002 • Contents: data delivered in IPP (inter-process protocol) format (non-FITS!). Available data consists of: • high, medium, and low downlink data • status messages • Data Volume: Total volume in archive: 105 Gbytes
HETE-2 website: http://heasarc.gsfc.nasa.gov/docs/hete2/ • Mission description & links to MIT website • Data ftp/http access and retrieval • Data descriptions • HETE-2 Science results • HETE-2 tables • HETEGCN: lists each HETE-2 trigger and “best” position • HETE-2 helpdesk (3 contacts)
Last HUG meeting: • (17) HUG: There is an urgent need to get the HETE-2 data in documented FITS formats • Current Status: • We now have scripts available to split out science instrument data (still in IPP format) • We have generated standard FITS 4 color lightcurves for GRBs (All public GRB datasets) • Also data in ASCII, and postscript plots (GRB lightcurves, housekeeping, etc) • Some documentation on data products
Under Development: • Develop HETE-2 “as flown” timeline table • User software & documentation • HETE archive access via BROWSE • FITS Data products for WXM and SXC
