  • bins.divide_1D: Divide data along 1 axis.
  • bins.divide_ND: Divide data along N axes.
  • bins.bin_by_index: Bins data by index.

• File utility:

  • files.create_folder: To create folders.
  • Functions for opening and outputting info on hdf5 files:
    • files.get_hdf5_keys to print the hdf5 keys and file structure.
    • files.get_hdf5_data retrieves the data of interest which is specified by the hdf5 keys.

• Gaussian Processes:

  • gp.GaussianProcesses: Class wrapping george's Gaussian Process fitting function for a 1D function.

• Masking functions:
