Photometric data catalogues and tools:

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.

Désert et al. 2015 phot Spitzer Space Telescope satelliteInfrared Array Camera (IRAC)1DESERT ET AL 2015 We use Warm-Spitzer/IRAC (Werner et al. 2004;Fazio et al. 2004) at 4.5 to observe transits of the 51 selected KOIs between May 2010 and July 2012. We obtained these observations as part of two large Science Exploration Programs (program ID 60028 and 80117). In total, 1400 hours of Spitzer time is used for the follow-up of Kepler targets. As described in Desert et al. (2011a), we use a transit light curve model multiplied by instrumental decorrelation functions to measure the transit parameters andtheir uncertainties from the Spitze rdata. We computethe transit light curves with the IDL transit routine OCCULTSMALL from Mandel & Agol (2002). This modeldepends on the following parameters: the planet-to-starradius ratio ; the orbital semi-major axis to stellar-radius ratio (system scale);, the impact parameter b, the time of mid transit Tc, and limb darkening coefficients.
Désert et al. 2015 phot The Kepler MissionKepler CCD Array1DESERT ET AL 2015 Kepler detects transiting planetary candidates signals through continuous photometric monitoring of about 160 000 stars at high photometric precision We use Spitzer observations to rule-out false positive scenarios. The applied methodology makes use of the transit depths measured with Spitzer and with Kepler
