[Connaughton et al. 2015, ApJS, 216, 32] ).\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 68\ndegrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2022/bn220528259/quicklook/glg_skymap_all_bn220528259.png\n\nThe HEALPix FITS file, including the estimated localization systematic, can\nbe found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2022/bn220528259/quicklook/glg_healpix_all_bn220528259.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2022/bn220528259/quicklook/glg_lc_medres34_bn220528259.gif",
