name of the identifier to query.

if set to `True` then returns the dictionary sent as the HTTP

--------

A query function similar to
`astroquery.ipac.irsa.irsa_dust.IrsaDustClass.get_images` but returns
file-handlers to the remote files rather than downloading
them. Useful for asynchronous queries so that the actual download
may be performed later.
Parameters
----------
coordinate : str
Can be either the name of an object or a coordinate string
If a name, must be resolvable by NED, SIMBAD, 2MASS, or SWAS.
Examples of acceptable coordinate strings, can be found `here.
<https://irsa.ipac.caltech.edu/applications/DUST/docs/coordinate.html>`_
radius : str / `~astropy.units.Quantity`, optional
The size of the region to include in the dust query, in radian,
degree or hour as per format specified by
`~astropy.coordinates.Angle` or `~astropy.units.Quantity`.
Defaults to 5 degrees.
image_type : str, optional
When missing returns for all the images. Otherwise returns only
for image of the specified type which must be one of
``'temperature'``, ``'ebv'``, ``'100um'``. Defaults to `None`.
timeout : int, optional
Time limit for establishing successful connection with remote
server. Defaults to `~astroquery.ipac.irsa.irsa_dust.IrsaDustClass.TIMEOUT`.
get_query_payload : bool, optional
If `True` then returns the dictionary of query parameters, posted
to remote server. Defaults to `False`.
Returns
-------
list : list
A list of context-managers that yield readable file-like objects.
