"""
Return the raw CRM points for a specific flight condition.
Any AoA from [2.50, 2.75, 3.00, 3.25, 3.50, 3.75, 4.00].
Or 'jig' or 'jig_wind_tunnel', for the undeformed wing based on the initial
paper definition and the wind tunnel model, respectively.
Parameters
----------
wing_type : string
Description of the wing type to use. Example is `CRM:alpha_2.75`.
Can use `CRM` for just the jig shape
Returns
-------
raw_crm_points[n, 6] : numpy array
The actual data points describing the CRM wing for the OpenAeroStruct
formatted definition at n spanwise slices.
