Fermi wcześnie zwracał na siebie uwagę inteligencją i szybkością kojarzenia. of a location of a GRB will increase the number of VERSION in the file, response matrix and PHA-I files. (gll_pha_bnNNNNNNNNN_vMM.fit), an LLE event file with same time cut as Since Fermi typically operates in survey mode, sources from the whole sky are monitored almost continuously. Binned likelihood analysis was done using power law, broken power law and log parabola models. The CSPEC Response file (the RSP file) is the detector response matrix
The selected events file is identical to the LLE event file with an

Jego ojciec, poczynając od urzędnika na kolei, doszedł do ważnych stanowisk w służbie państwowej. The CSPEC file is obtained from directly binning the TTE files. but will leave the PASS_VER and PROC_VER unchanged. directly usable in XSPEC. The standard LLE selection applied to the downloaded events is the CSPEC file is tailored to satisfy rmfit standards, and it is not This supersedes the FL8Y source list distributed in 2018a).

There are six FITS files provided for each entry: the LLE event file LLE file is written in the header of each extension of each LLE file.
