create_ecl_to_eq_rotation_matrix(ecl)[source]

Creates a rotation matrix for transforming ecliptical coordinates to equatorial coordinates. A rotation matrix based on the solar system's ecliptic obliquity is already provided as ECL_TO_EQ_ROTATION_MATRIX.

Parameters:: ecl (float) -- The ecliptical obliquity.
Returns:: rotmat -- rotation matrix for transofmring ecliptical coordinates to equatorial coordinates. Array has shape (3,3).
Return type:: numpy array/matrix of floats
