OGLE Queries (astroquery.ogle)¶
Getting started¶
The Optical Gravitational Lensing Experiment III (OGLE-III) stores information
on the interstellar extinction towards the Galactic Bulge. The
astroquery.ogle module queries the online extinction calculator and returns
an Table instance with the same data. To run a single query
using an astropy.coordinates instance use:
>>> from astropy import coordinates
>>> from astropy import units as u
>>> from astroquery.ogle import Ogle
>>> co = coordinates.SkyCoord(0*u.deg, 3*u.deg, frame='galactic')
>>> t = Ogle.query_region(coord=co)
Arguments can be passed to choose the interpolation algorithm, quality factor,
and coordinate system. Multiple coordinates may be queried simultaneously by
passing a list-like object of string/float values or a list-like object of
astropy.coordinates instances. All of coordinates will be internally converted
to FK5.
>>> # list of coordinate instances
>>> co_list = [co, co, co]
>>> t1 = Ogle.query_region(coord=co_list)
>>> # (2 x N) list of values
>>> co_list_values = [[0, 0, 0], [3, 3, 3]]
>>> t2 = Ogle.query_region(coord=co_list_values, coord_sys='LB')
Note that non-Astropy coordinates may not be supported in a future version.
