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

FOT tape data have been filed to disk
setting of the appropriate environment variables is complete
a valid observation chain has been defined.

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.
