Astro-E2 data at the HEASARC Koji Mukai NASA/GSFC and USRA
Mission Summary • Astro-E2 is a Japanese-US mission to be launched in 2005 February. • Three types of co-aligned instruments will produce events list and other standard FITS files. • 1 XRS (6x6 array microcalorimeter with coarse imaging) • 4 XIS (CCD-based imaging spectrometer) • 1 HXD (collimated hard X-ray detector with variable field-of-view)
Instrument Summary • XRS: High-resolution, non-dispersive spectrometer. • Bandpass: 0.3-12 keV (150 sq. cm at 6 keV) • Spectral resolution: 6 eV • XIS: Large-area imaging spectrometer. • Bandpass: 0.4-12 keV (1000 sq. cm at 6 keV) • HXD: Low-bgd hard X-ray detector. • Bandpass: 10-600 keV (300 sq. cm at 120 keV) • Collimator: 0.56 deg below 100 keV, 4.6 deg at >200 keV.
Data Volume and Access • Maximum Telemetry Rate: 10 Gbit/day. • Actual data rate will depend on source brightness and HXD background rate (of the order of 1 Gbyte/day?). • Mission life: ~2.5 years for the XRS, with additional ~5 years with the remaining instruments. • Access via ftp, with PGP-encryption while proprietary.
Data Processing • Raw telemetry to be archived at ISAS. • Initial FITS conversion and attitude file creation at ISAS. • Parallel processing of data at GSFC and at ISAS, using pipeline architecture developed for ASCA. • Component FTOOLS written for ASTRO-E can be adopted easily. • Pipeline scripts also exist. • Data will be archived at ISAS and at HEASARC.
Potential Issues • Parallel data processing at ISAS and at ISAS and at GSFC - requires tight version control of processing software and calibration data. • HXD anti-coincidence counters has the potential as a GRB, transient, and bright source monitor (a la BATSE). • No agreement on data right issue. • Data processing yet to be defined.
