1. Effective Area, Filter Transmission, Quantum Efficiency and Grating attenuation
... arfgen (arfgen-1.73.3) [?? ... arfgen simply constructs the appropriate quantities from the CAL, in the form of vectors of discrete energy-dependent elements, and combines these data multiplicatively to form the ancilliary response. ... This is already taken into account by the CAL in the call to CAL_effectiveArea. The user can enable or disable the effective area, filter transmission, QE or grating attenuation by setting the relevant parameter (eg modeleffarea ) to true or false respectively. ...
