Data Preparation Threads:

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.

• Preparing to Run ChaRT

• Run ChaRT

• Retrieve ChaRT Ray Files

After running ChaRT, the simulated PSF must be projected onto onto the detector-plane. This is done with MARX, which includes the detector response.

• Using MARX to Create an Event File

It is also possible to 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.

• Creating an Input Spectrum for Running MARX Simulations

Data Analysis Threads:

The pseudo-event file produced from projecting the simulated rays to the detector-plane may be binned into an image that matches the data and used during science analysis.

• Creating an Image of the PSF

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