Example use

Converting celestial to pixel coordinates:

>>> from tess_locator import locate
>>> locate("Alpha Cen")
List of 3 coordinates
↳[TessCoord(sector=11, camera=2, ccd=2, column=1699.1, row=1860.3, time=None)
  TessCoord(sector=12, camera=2, ccd=1, column=359.9, row=1838.7, time=None)
  TessCoord(sector=38, camera=2, ccd=2, column=941.1, row=1953.7, time=None)]

Obtaining pixel coordinates for a specific time:

>>> locate("Alpha Cen", time="2019-04-28")
List of 1 coordinates
↳[TessCoord(sector=11, camera=2, ccd=2, column=1699.1, row=1860.3, time=2019-04-28 00:00:00)]

• tess-point is the package being called behind the scenes. Compared to tess-point, we add a user-friendly API and the ability to specify the time, which is important for moving objects.

• astroquery.mast includes the excellent TesscutClass.get_sectors() method which queries a web API. This package provides an offline version of that service, and adds the ability to query by time.

• tess-waldo lets you visualize how a target moves over the detector across sectors. It queries the TessCut service to obtain this information. This package adds the ability to create such plots offline.
