Spectral hardness of X- and gamma-ray emissions from lightning stepped and dart leaders

This repository has four folders dedicated to the 11 triggers outlined in the manuscript. Within each folder, the data is organized according to the four sensors:

1. Slow Antenna Folder: For every trigger, there is a corresponding .asc file paired with a complementary .readme file. Additionally, this folder includes a .txt file that lists the file names and UTC times.
2. LEFA: The *.txt files within this section consist of four columns representing seconds after midnight (UTC), instrument power voltage, sensitive channel, medium channel, and unsensitive channel. The file names adhere to the format lefa2-yymmdd-hhmm00.txt, each containing one minute of LEFA data.
3. DAS: Files in this category follow the format XRAY_yyyy.mm.dd_hh-mm-ss_milliseconds.channel[B,C, or D].csv, with UTC time. The file name corresponds to time zero in the data. The first column denotes seconds from/after zero, while the second column represents the measured data in Volts. The channels (B, C, D) correspond to Fast Antenna, LaBr detector, and NaI detector, respectively. The instrument has a sampling rate of 180 MHz.
4. Fieldmill:The file names in this section adhere to the format kv2022mmdd-hhmm.flt and are accompanied by a calibration file.
