Usage
-----------------------------------------

Main function is Mshpy.msh_param, which provides magnetosheath parameters along certain spacecraft orbit.

Args:
    1. path: File directory to save outputs.
    2. Start time: in the format of '2012-03-01T02:00'
    3. End time: in the same format
    4. Spacecraft name. It should be same as one used in SscWs. See https://sscweb.gsfc.nasa.gov/WebServices/REST/jupyter/SscWsExample.html.
    5. mpoff: Optional; Manual magnetopause offset along x axis.
        Magnetopause model for the MHD-based MSH model is Shue et al. 1998.
    6. bsoff: Optional; Manual bow shock offset along x axis
        Bow shock model for the MHD-based MSH model is Jelinek et al. 2012
