spacepy.irbempy.coord_trans¶
- spacepy.irbempy.coord_trans(loci, returntype, returncarsph)[source]¶
thin layer to call coor_trans1 from irbem lib this will convert between systems GDZ, GEO, GSM, GSE, SM, GEI, MAG, SPH, RLL
- Parameters:
- - loci (Coords instance)containing coordinate information, can contain n points
- - returntype (str)describing system as GDZ, GEO, GSM, GSE, SM, GEI, MAG, SPH, RLL
- - returncarsph (str)cartesian or spherical units ‘car’, ‘sph’
- Returns:
- - xout (ndarray)values after transformation in (n,3) dimensions

Examples
>>> c = Coords([[3,0,0],[2,0,0]], 'GEO', 'car', use_irbem=True) >>> c.ticks = Ticktock(['2002-02-02T12:00:00', '2002-02-02T12:10:00'], 'ISO') >>> coord_trans(c, 'GSM', 'car') array([[ 2.8639301 , -0.01848784, 0.89306361], [ 1.9124434 , 0.07209424, 0.58082929]])
