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')
>>> c.ticks = Ticktock(['2002-02-02T12:00:00', '2002-02-02T12:10:00'], 'ISO')
>>> coord_trans(c, 'GSM', 'car')
