This script combines executables performing the background correction in accordance with the chosen method.

As the output for each energy range for ISGRI shadowgrams of larger dimensions (corrected expanded shadowgram and corresponding variance and efficiency expanded shadowgrams) are written to ISGR-CEXP-SHD. The energy range is given in the keywords E_MIN, E_MAX, CHAN_MIN, CHAN_MAX, and a shadowgram type is given by SHD_TYPE keyword.

For PICsIT Data Structures PICS-CEXP-SHD and PICS-VEXP-SHD are filled for the corrected expanded detector shadowgram and the corrected expanded variance detector shadowgram. The energy range is again given in the keywords.
