All the necessary data and scripts to reproduce You B., et al., (2023)

• Multi-wavelengths observation data folder contains the data points which are plotted in Fig. 1、2、4, and Fig. S7、S8.

• Time-delay folder contains

  (i) the script piccf_mc.c which uses the data points in Fig. 2 to determine the lags between flares of different wavelengths;

  (ii) the script iccf.py is used to plot the relevant results in Fig. S1.

• Formation of a MAD folder contains one script code.ipynb which is used to plot Fig. S3-S6. The source code which simulates the magnetic field is also provided.

• Simulation of a DIM folder contains the source code which simulates the DIM.
