download_cutouts
(coordinates=None, size=5, sector=None, path='.', inflate=True, objectname=None)[source]¶ Download cutout target pixel file(s) around the given coordinates with indicated size.
Parameters: coordinates : str or
astropy.coordinates
object, optionalThe target around which to search. It may be specified as a string or as the appropriate
astropy.coordinates
object. One and only one of coordinates and objectname must be supplied.size : int, array-like,
Quantity
Optional, default 5 pixels. The size of the cutout array. If
size
is a scalar number or a scalarQuantity
, then a square cutout ofsize
will be created. Ifsize
has two elements, they should be in(ny, nx)
order. Scalar numbers insize
are assumed to be in units of pixels.Quantity
objects must be in pixel or angular units.sector : int
Optional. The TESS sector to return the cutout from. If not supplied, cutouts from all available sectors on which the coordinate appears will be returned.
path : str
Optional. The directory in which the cutouts will be saved. Defaults to current directory.
inflate : bool
Optional, default True. Cutout target pixel files are returned from the server in a zip file, by default they will be inflated and the zip will be removed. Set inflate to false to stop before the inflate step.
objectname : str, optional
The target around which to search, by name (objectname=”M104”) or TIC ID (objectname=”TIC 141914082”). One and only one of coordinates and objectname must be supplied.
Returns: response :

Returns: response : A list of
HDUList
objects.

get_sectors
(coordinates=None, radius=<Quantity 0.2 deg>, objectname=None)[source]¶ Get a list of the TESS data sectors whose footprints intersect with the given search area.
Parameters: coordinates : str or
astropy.coordinates
object, optionalThe target around which to search. It may be specified as a string or as the appropriate
astropy.coordinates
object. One and only one of coordinates and objectname must be supplied.radius : str, float, or
Quantity
object, optionalDefault 0.2 degrees. If supplied as a float degrees is the assumed unit. The string must be parsable by
Angle
. The appropriateQuantity
object fromastropy.units
may also be used.objectname : str, optional
The target around which to search, by name (objectname=”M104”) or TIC ID (objectname=”TIC 141914082”). One and only one of coordinates and objectname must be supplied.
Returns: response :
