"s3://stpubdata/tess/public/ffi/s0014/2019/199/2-3/tess2019199202929-s0014-2-3-0150-s_ffic.fits"

List the images of a TESS sector:

>>> tess_cloud.list_images(sector=5, camera=2, ccd=3)
<TessImageList>

Read a TESS image from S3 into local memory:

>>> from tess_cloud import TessImage
>>> img = TessImage("tess2019199202929-s0014-2-3-0150-s_ffic.fits")
>>> img.read()
<astropy.io.fits.HDUList>

Read only the header of a TESS image into local memory:

>>> img.read_header(ext=1)
<astropy.io.fits.FitsHeader>

Cutout a Target Pixel File for a stationary object:

>>> from tess_cloud import cutout
>>> cutout("Alpha Cen", shape=(10, 10))

TESScut is an excellent API service which allows cut outs to be obtained for stationary objects. Tess-cloud provides an alternative implementation of this service by leveraging the TESS public data set on AWS S3.

At this time tess-cloud is an experiment, we recommend that you keep using TESScut for now!
