get_tess_sectors

astrocut.get_tess_sectors(coordinates: str | SkyCoord, cutout_size: int | Quantity | List[int] | Tuple[int]) → Table[source]

Return the TESS sectors (sequence, camera, CCD) whose FFI footprints overlap the given cutout defined by position and size.

Parameters:

coordinatesstr or astropy.coordinates.SkyCoord object

The position around which to cutout. It may be specified as a string (“ra dec” in degrees) or as the appropriate SkyCoord object.

cutout_sizeint, array-like, or Quantity

The size of the cutout array. If cutout_size is a scalar number or a scalar Quantity, then a square cutout of cutout_size will be used. If cutout_size has two elements, they should be in (ny, nx) order. Scalar numbers in cutout_size are assumed to be in units of pixels. Quantity objects must be in pixel or angular units.

If a cutout size of zero is provided, the function will return sectors that contain the exact RA and Dec position. If a non-zero cutout size is provided, the function will return sectors whose footprints overlap with the cutout area.

Returns:

Table: A table containing the sector name, sector number, camera number, and CCD number for each sector that contains the specified coordinates within the cutout size.
