If the event data have passed through the
Townsley et al. CTI corrector,
AE can be configured to select a response matrix file (RMF) for each source in each observation from a set of RMFs supplied with the CTI corrector.
If the data come from standard CXC processing, AE can be configured to construct an RMF using the CIAO tool mkacisrmf or mkrmf.
In a multi-observation reduction, a multi-ObsId RMF is constructed using the FTOOL addrmf, using the observation's EXPOSURE keywords as the weights.
