[docs]class GBMClient(GenericClient): """ Provides access to data from the Gamma-Ray Burst Monitor (GBM) instrument on board the Fermi satellite. Although GBMs primary objective is to detect gamma-ray bursts, it provides high quality high energy solar flare observations. The instrument consists of 12 Sodium Iodide (NaI) scintillation detectors, which are sensitive to an energy range of 4keV to 1MeV. At any one time, 6 of the NaI detectors are Sunward facing. The detectors are numbered 'n1' to 'n11'. This client supports the user to choose which detector to use through the `a.Detector <>` attribute. The default detector is 'n5'. The GBM data comes in daily version files in two formats: * CSPEC - counts accumulated every 4.096 seconds in 128 energy channels for each detector. * CTIME - counts accumulated every 0.256 seconds in 8 energy channels Both of which can be accessed through the attrs `a.Resolution <>`. The default data type is CSPEC unless the user defines.
