Query the OGLE-III interstellar extinction calculator.
| Parameters : | coord : list-like
Pointings to evaluate interstellar extinction. Three forms of
coordinates may be passed:
- single astropy coordinate instance
- list-like object (1 x N) of astropy coordinate instances
- list-like object (2 x N) of RA/Decs or Glon/Glat as strings or
floats. (May not be supported in future versions.)
algorithm : string
- Algorithm to interpolate data for desired coordinate. Valid options:
- ‘NG’: nearest grid point
- ‘NN’: natural neighbor interpolation
quality : string
- Quality factor for data. Valid options:
- ‘All’: all points
- ‘GOOD’: QF=0 as described in Nataf et al. (2012).
coord_sys : string
- Coordinate system if using lists of RA/Decs in coord. Valid options:
- ‘RD’: equatorial coordinates
- ‘LB’: Galactic coordinates.

Examples
Using astropy coordinates:
>>> from astropy import coordinates as coord
>>> from astropy import units as u
>>> co = coord.Galactic(0.0, 3.0, unit=(u.degree, u.degree))
>>> t = ogle.query(co)
>>> t.pprint()
