The software publcation contains a python script which can be used for enhanced visualization of inverse time-temperature models created with the HeFTy Software v2.1.7 (Ketcham, 2005, 2024; Ketcham et al., 2007). The script was generated and tested using a Spyder IDE 5.1 (conda) kernel with Anaconda Navigator v2.6.0. The output is a heatmap based on time-temperature path density, which is calculated by interpolating between the paths' turning points on a raster of 1Ma and 1°C. Processable data are inverse modelling export files (.txt) from the HeFTy software (v2.1.7). To generate a proper file in HeFTy, activate "inverse modelling", rightclick on the "time-temperature" panel, choose "Export" -> "Save as text". Please also consider the "REQUIRED USER INPUT" section of the script.
