TESS OBSERVATIONS

Light curve files contain flux time series data and are produced for each target using simple aperture photometry. These are used to search for transiting planets and other astrophysical phenomena. The flux and uncertainties are provided at each cadence, with NaNs filling in any missing data values. TESS light curves are FITS format files that contain the output of the photometric extraction and subsequent systematics removal (cotrending) performed by the SPOC algorithms. A single light curve file contains the data for one target for on observing sector. If a target was observed in more than one TESS sector, multiple light curve files will be created but they may be made available on the MAST in separate deliveries.
Here there are the plotted Light Curves from each Observation Fits file whit the Data validation auxiliary products created by the Tess pipeline.

Knutson et al. 2011 phot Spitzer Space Telescope satelliteInfrared Array Camera (IRAC)8KNUTSON ET AL 2011 : we describe a uniform analysis of eight transits and eleven secondary eclipses of the extrasolar planet GJ 436b obtained in the 3.6, 4.5, and 8.0 microns bands using the IRAC instrument on theSpitzer Space Telescope between UT 2007 June 29 and UT 2009 Feb 4. We analyze nineteen separate observations of GJ 436, including two 3.6 microns transits, two 4.5 transits, four 8 microns transits, and eleven 8 mcrons secondary eclipses, as listed in Table 1
Knutson et al. 2014 spec Hubble Space Telescope satelliteWide Field Camera 328KNUTSON ET AL 2014: We observed four transits of the Neptune-mass planet GJ 436b on UT Oct 26, Nov 29, and Dec 10 2012, and Jan 2 2013 using the red grism (1.2-1.6 μm) in a new scanning mode. We fit the four wavelength-integrated (white-light) transit curves simultaneously while accounting for detector effects (see discussion in Supplemental Methods)
