Space‐Based Detection and Data Analysis in Practice: Analysis and Correction of Swift GRB Data

Our work focuses on the analysis and correction of gamma‐ray burst (GRB) data, with particular emphasis on the NASA GCN (Gamma‐ray Coordinates Network) database and the Swift space telescope observations. The research has involved a comprehensive analysis of GCN reports, the systematization of the Swift GRB table data and the correction of redshift values. I contacted the NASA GCN team to gain access to the limited data and made suggestions for the restoration of unavailable sub‐sites. I then compared the GCN data with the Johannes Greiner BIG Table database. During the comparison I found that the BIG Table contained inaccurate data in some cases, which highlighted the importance of data revision. The results of this study highlight the shortcomings of the GRB redshift data, which is of concern as these data are crucial for determining the cosmological distance of GRBs.
