PSF Simulations
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.

- Creating an Image of the PSF
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.
- Using MARX to Simulate an Existing Observation
- Using MARX to Simulate a Planned Observation
Data Analysis Threads
-
The PSF effects may also be accounted for during 2D image
fitting.
