- OXS Effective Area
- An extended source emitting a He-like line series can be mapped in
each spectral feature by combining data from a series of observations,
each with a slightly different orientation of the crystal panel and
telescope pointing direction. In any one orientation, specific regions
of the source, as shown here, will satisfy the Bragg conditions for
the Forbidden,
Intercombination, and Resonance line energies and
thus be imaged into
corresponding regions on the detector. Different crystal/telescope
orientations will sample different regions of the source.

counts cm-2 s-1 keV-1 (instrumental)
and
counts cm-2 s-1 keV-1 pixel-1(cosmic) are assumed.
