...simultaneously

Due to the shutter configuration and the read-out constraints, the red spectral integrations had to be terminated and read-out 60s before the blue.

...1996)

Short term spectral variability in the soft ASCA band is known to occur during this observation (Otani et al. 1996), and one might worry about the effect of this variability when one performs spectral fitting on the time-averaged spectrum. However, it is known that changes in 116#116 dominate this spectral variability. Thus, the best fitting parameters for the outer warm absorber (which contributes very little to the OVIII edge) should be relatively unaffected by spectral variability

...coronal

In this context, the term `coronal flux' is used to mean that radiation which is associated with the X-ray emitting disk-corona, and is unrelated to the `coronal line emission' discussed in Section 5.
