6. Accumulating spectra, images, time profiles
Accumulation is the process of generating data structures (like images,
spectra, time profiles and photon lists) in a
mission-independent format
starting from telemetry files.
As prerequisites one shall ensure that
One can accumulate directly "reduced" data structures of immediate
usage (like spectra, images or light curves) or pass thru intermediate
photon lists. The latter are described in another section.
