The Fermi Gamma-ray Space Telescope was launched in June 2008 to explore high-energy phenomena in the Universe. We provide quicklook products, data archives, and analysis software for both Gamma-ray Burst Monitor (GBM) and Large Area Telescope (LAT) targeted for the solar physics community.
Summary of GBM and LAT Data
What we provide:
|GBM Solar Flare List||Autonomous flare finder identifies all flares ≥ GOES C-Class detected by GBM above 10 keV. (FITS file)|
|GBM Quicklook Daily and Orbital Plots||Time histories of NaI, GBO, and GOES data, with flare and day/night markers. Orbital plots are on RHESSI orbit times.|
|GBM Response Matrix FITS Files||Time-dependent detector response matrices for each GBM detector covering the duration of every GBM flare. Needed in the spectral analysis software to relate observed count-rate spectra to model photon spectra. Suitable for analyzing CPEC and CTIME data.|
LAT 4-day Quicklook Plots
(not yet available on RHESSI Browser)
LAT solar gamma-ray flux > 100 MeV, one point per solar exposure (i.e. average of the 20-40
minutes of solar observation every ~1.5 hours).
Direct Link to PNG files: 4-day plots
|LAT Daily Lightcurve FITS Files||LAT data between 100 MeV and 10 GeV filtered for solar counts in 1-minute time bins, no energy binning. Contains exposure (cm^2 s) information.|
|LAT Daily Spectrum FITS Files||LAT data filtered for solar counts in 1-minute time bins, 10 energy bins from 30 MeV to 10 GeV. Used as the basis for the LAT quicklook plots, and as input to the OSPEX spectral analysis software.|
|LAT Response Matrix FITS Files||LAT detector response matrices for each solar exposure period (20-40 minutes every ~1.5 hours).|
GBM Spectral Analysis
LAT Spectral Analysis (coming soon)
IDL spectral analysis software package, is used to
For GBM, input is daily or trigger CSPEC or CTIME file from Fermi archive and corresponding response file from our archive. For LAT, input is daily spectrum file and corresponding response file, both from our archive.
See the OSPEX Guide for more information.
|IDL Utility Routines||Useful SSW IDL routines for Fermi solar data analysis.|
