Skyview Queries (`astroquery.skyview`)
**************************************
Getting started
===============
The `SkyView <https://skyview.gsfc.nasa.gov/>`_ service offers a cutout service for a
number of imaging surveys.
To see the list of surveys, use the `~astroquery.skyview.SkyViewClass.list_surveys` method. Note that the list here is not necessarily up-to-date; if SkyView has added surveys recently, they will appear when you run this code:
.. code-block:: python
>>> from astroquery.skyview import SkyView

There are two essential methods:
`~astroquery.skyview.SkyViewClass.get_images` searches for and downloads
files, while `~astroquery.skyview.SkyViewClass.get_image_list` just searches
for the files.
.. code-block:: python
>>> paths = SkyView.get_images(position='Eta Carinae',
... survey=['Fermi 5', 'HRI', 'DSS'])
