| Abstract: | The science analysis of the data from the High Energy X-ray Telescope(HE) on the Hard X-ray Modulation Telescope(HXMT) satellite is organized in three stages:calibration,screening and extraction of high-level scientific products.At the first stage,the raw PHA value of each event is converted to PI value accounting for temporal changes in gain and energy offset.At the second stage,the calibrated events are screened by applying cleaning criteria.At the third stage,scientific products,i.e.spectra,light curves and redistribution matrix files,are extracted.This work will introduce the three stages as well as the screening criteria and the data combining method. |
