EP-FXT Data Analysis Software Releases New Version 1.20

On May 30, 2025, the EP-FXT team released version 1.20 for the data analysis software (FXTDAS) and the associated calibration database (CalDB). This release includes significant improvements to FXTDAS and updates to the CalDB, based on the latest in-orbit calibration of FXT. Compared to v1.10, version 1.20 delivers improvements in data processing performance, offers additional modules and functionalities, and incorporates more accurate calibration. The software package and calibration files are available for download at: http://epfxt.ihep.ac.cn/analysis.  

Version 1.20 Updates:

Data Analysis Software:

1. Added an instrumental background estimate module (fxtbkggen);

2. Added PSF image and EEF estimate modules (fxtpsfgen and fxteefgen);

3. Updated the exposure map module (fxtexpogen): improved computation speed and added an edge mask function;

4. Update the pipeline module (fxtchain) to support both ‘evt’ data and ‘fsaevt’ data.

Calibration Database:

1. Updated the E-C relationship;

2. Updated the energy resolution;

3. Updated the Ancillary Response File (ARF), suitable for the energy band of 0.5-10 keV in this version.

Bug Fixes:

1. Adjusted the energy precision of ARF file to match that of RMF file;

2. Added keywords TLMIN4=0 and TLMAX4=1023 to RMF file.
