The EP-FXT team is pleased to announce the release of FXTDAS version 1.20, the latest update to the data analysis software for the Einstein Probe Follow-up X-ray Telescope (EP-FXT). This release introduces several new features and optimizations compared to last version 1.10.
Key Updates in Version 1.20
1. Added an instrumental background estimation module (fxtbkggen) for extended source analysis. The estimation is based on the spectrum of cleaned events in frame-store area (FSA).
2. Added PSF image and EEF estimation modules (fxtpsfgen and fxteefgen) for any detector position (rawX and rawY) and any energy (eV).
3. Optimazed the exposure map calculation method in fxtexpogen. Added the parameter 'edgecovermask' to mark the 20 rows near the readout side as 0 in the exposure map. Added the parameter 'area_scale' for scaling the effective area.
4. Added support of the analysis of fsaevt data in the pipeline tool (fxtchain). The spectrum of the cleaned events in FSA can be obtained by running fxtchain with the parameter set to ‘datatype=fsaevt’.
You can download the source code of FXTDAS. In addition, the docker image is also provided. If you encounter any installation problem, it is recommended to use the docker version.
