ChaRT is easily run with a few input parameters, producing output data files that contain the simulated HRMA PSF. The following threads illustrate collecting the necessary input for ChaRT, unpacking and identifying the output files and the final step of projecting the HRMA PSF onto the detector-plane.

Steps to Run ChaRT Simulations
Using ChaRT Outputs

After running ChaRT, the simulated PSF must be projected onto onto the detector-plane—this is done with MARX, which includes the detector response—and an image file may be created from the projected event file.

MARX Spectrum

It is also possible to use the intrinsic MARX instrument and HRMA models to perform raytracing. If a PSF with a source spectrum is desired, then a MARX-compatible input spectrum may be created.

MARX Examples

The internal MARX HRMA model may also be used to run raytracing simulations, and two use-cases are described.

The PSF effects may also be accounted for during 2D image fitting.
