The operation and data processing of the Einstein Probe FXT science data center

Background: The Einstein Probe (EP) is a space X-ray astronomical mission of China-Europe collaboration, launched on January 9, 2024, and is equipped with two types of scientific payloads, the wide-field X-ray telescope (WXT) and the follow-up X-ray telescope (FXT).
Methods: The FXT payload was developed by the Institute of High Energy Physics (IHEP). Consequently, the EP-FXT Science Data Center (SDC) was established at IHEP to manage the processing of FXT data.
Results and conclusion: The EP-FXT SDC has maintained a continuous and stable operation since the EP’s launch. It has provided the standard data products, released the data analysis software and calibration database, and supported the science users in conducting scientific research. In this paper, we present a systematic and comprehensive overview of the primary workflows and key tasks of the FXT science data center.
