Generation from Ground Calibration Data

A spatial and spectral information of the diffuse galactic light emission is taken from literature: The spatial distribution of the DGL is contained in the DGL_MAP extension. The galactic coordinate system is used.
The spectrum is compiled from literature and written into the extension DGL_SPEC. The intensity of the spectrum is scaled to the reference intensity. The photon rate are estimated by folding the DGL spectrum with OSIM. The binary table DGL_CTS lists the expected photon rates for the different filters at the reference intensity.
