Simulating Soft X-ray Images of the Magnetosheath

Simulations of the soft X-ray emission from the magnetosheath are required in order to determine the extent to which proposed missions will be able to determine the location of the magnetopause and bowshock. Simulating the soft X-ray images of the magnetosheath requires a wide array of models (see talks by Collado-Vega and Connor), astronomical measurements, and atomic data. The first part of this presentation will discuss the way the charge exchange emission is calculated from these components, and will concentrate on the sources of uncertainty. The second part of this presentation will discuss methods for determining the location of the magnetopause within the simulation images so that the location of the nose of the magnetosheath can be reconstructed (see talk by Collier). This presentation will finish with a calculation of the uncertainty in the location of the magnetopause within an X-ray image.
