Jupyter Notebook Tutorials

  • PHAII Data Tutorial

    PHAII data is one of the primary types of science data provided by GBM, and is temporally pre-binned. The two types of PHAII data are CSPEC and CTIME, where CSPEC has 128 energy channels and CTIME has 8 energy channels. Learn how to plot the lightcurves and count spectra of gamma-ray bursts using CSPEC and CTIME data.

  • TTE Data Tutorial

    TTE (Time-Tagged Event) data is one of the primary types of science data provided by GBM, and is temporally unbinned. Learn how to plot the lightcurves and count spectra of gamma-ray bursts using TTE data.

  • Detector Responses Tutorial

    Detector response files allow you to compare a theoretical photon spectrum to an observed count spectrum. The two types of detector response files are rsp and rsp2 files, where rsp contain a single DRM (Detector Response Matrix), and rsp2 contain more than one DRM. Learn how to read, manipulate, and plot detector response ‘rsp2’ data.

  • Position History Data Tutorial

    Position history (POSHIST) data contains the spacecraft location in orbit and pointing information for an entire day. Learn how to open, read, and plot position history data.

  • Trigger Data Tutorial

    Trigger data (TRIGDAT) was designed to contain the minimum amount of data required for rapid on-ground characterization and localization of triggers. It contains pre-binned lightcurve data for each detector along with spacecraft position and attitude information. Learn how to plot the lightcurves of gamma-ray bursts and the positional data of the Fermi instrument using trigger data.

  • Localizations and Skymaps Tutorial

    GBM produces localizations for GRBs that contain the best-modeled systematic uncertainty in the localization, individual detector pointings, and the geocenter location as observed by Fermi. Localization information is contained in HEALPix FITS files. Learn how to access localizations for gamma-ray bursts and to plot skymaps, both of the localizations and of other known points, using HEALPix files.

  • Finding GBM Data Tutorial

    GBM Data is hosted publicly on the HEASARC FTP server via the Fermi Science Support Center, and is stored in a consistent directory structure. Learn how to earch the HEASARC FTP server for trigger data and continuous data, as well as how to search the GBM catalogs.

  • Reduction and Export Tutorial

    Often, we would like to reduce GBM data and model the background so that we can examine the source spectrum. The following workflow will show you how you can do this and export the relevant data. Learn how to plot a lightcurve, complete a background fit, and write and export the results.

  • Spectral Analysis Tutorial

    Often, one would like to perform a spectral fit on GBM data. The following workflow will guide you through a simple example of this process. Learn how to fit GBM spectral data.

  • Spectral Catalog Data Tutorial

    GBM provides standard spectral fits for each GRB triggered on-board, which are hosted as Spectral Catalog (SCat) files that contain data such as fit parameters, uncertainties, fluxes/fluences, fit statistic, and covariance. Learn how to download, access, and manipulate SCat data.
