We add new modules for receiver lunction(RF) analysis in SplitLab toolbox,which includes the manual RF analysis module,automatic RF analysis and related quality control modules,and H-k stacking module.The updated toolbox(named SplitRFLab toolbox),especially its automatic RF analysis module,could calculate the RFs quickly and efficiently,which is very useful in RF analysis with huge amount of seismic data.China is now conducting the ChinArray project that plans to deploy thousands of portable stations across Chinese mainland.Our SplitRFLab toolbox may obtain reliable RF results quickly at the first time,which provide essentially new constraint to the crustal and mantle structures.
