Investigating FRB 20240114A with FAST: Morphological Classification and Drifting Rate Measurements in a Burst-Cluster Framework

This dataset accompanies the publication "Investigating FRB 20240114A with FAST: Morphological Classification and Drifting Rate Measurements in a Burst-Cluster Framework" (Zhang et al. 2025, arXiv:2507.14711). It includes observational results from FRB 20240114A collected by the Five-hundred-meter Aperture Spherical Telescope (FAST) on March 12, 2024 (UTC+8), focusing on morphological classification and frequency drifting behavior.The dataset consists of the following components:All_Drifting_Burst-Cluster_Table.xlsx: A catalog of all burst-clusters exhibiting measurable frequency drifting rates.Morphology/: Contains plots (*.png) and corresponding data files (*.ar) for each morphological class of burst-clusters.all_double-multi_consecutive_burst-clusters_for_K-S_test/: A subset of data from the Morphology folder, consisting of double- and multi-component burst-clusters with consecutive or mixed (consecutive and intermittent) time intervals, prepared for the Kolmogorov–Smirnov (K–S) statistical analysis.All files are in open formats (e.g., *.xlsx, *.png, *.txt, *.ar) and are intended to facilitate further analysis and reproducibility of our results.Note: The .ar (archival) file is a radio astronomy data format used by telescopes like FAST and Parkes to store raw or processed observations. It contains high-time-resolution dynamic spectra and metadata such as source info and instrument settings. The .ar files are commonly used in FRB and pulsar studies and can be read using software like PSRCHIVE, including its Python package psrchive for easy access and analysis.
