CORRECT

Applies exposure and dead time corrections to binned datasets. These corrections are performed using only standard instrument independent structures within your dataset (if present) and so should work on data from any source.

CORRECT gives the option of adding a variance array to its output if one is not present in its input. This enables (for example) swift progression from a simple binned spectrum to spectral fitting.

Note that if ASTERIX has an instrument interface for the dataset you are processing then you should check to see if there is a specialised application available - this is likely to do a better job than CORRECT. This is the case for all the EXOSAT, WFC and XRT interfaces.
