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.

Copperwheat et al. 2013 spec Hubble Space Telescope satelliteSpace Telescope Imaging Spectrograph3COPPERWHEAT ET AL 2013. An alternativce approach is to use simultaneous photometric observations in multiple wavebands to determine wavelength dependent transit depthdifferences. We report an application of this technique to one of the hottest known exoplanets, WASP-12b, using the triple-beam camera ULTRACAM. We obtained simultaneous light curves in Sloan u', and two narrow band filters centered on 0.416 and 0.6010 microns with FWHMs 0.0052 and 0.0118 microns respectively.
Kreidberg et al. 2015 spec Hubble Space Telescope satelliteWide Field Camera 313KREIDBERG ET AL 2015 . Here we report a precise near infrared transmission spectrum for WASP-12b based on six transit observations with the Hubble Space Telescope/Wide Field Camera 3. We bin the data in 13 spectrophotometric light curves from 0.84 to 1.67 microns and measure the transit depths to a median precision of 51 ppm.
Mandell et al. 2013 spec Hubble Space Telescope satelliteWide Field Camera 319MANDELL ET AL 2013 the observations of WASP-12 were obtained in April of 2011. The observations were taken with the G141 grism on WFC3 infrared channel, providing slitless spectra covering the wavelength range 1.1 to 1.7 at a maximum resolving power of 130 at 1.4
Sing et al. 2013 spec Hubble Space Telescope satelliteSpace Telescope Imaging Spectrograph21SING ET AL 2013 We observed two transits of WASP-12b with the HST STIS G430L grating during 14 March 2012 and 27 March 2012, as well as one transit with the STIS G750L during 4 September 2012. The G430L and G750L datasets all consist of 53 spectra, each spanning five spacecraft orbits. The G430L grating covers the wavelength range from 0.2900 to 0.5700 microns, The G750L grating covers the wavelenght range from 0.5200 to 1.0270
Sing et al. 2013 phot Spitzer Space Telescope satelliteInfrared Array Camera (IRAC)2SING ET AL 2013 In this paper, we present new HST transit observations with the STIS instrument, and combine them with existing WFC3 spectra and Spitzer photometry to construct a high signal-to-noise near-UV to infrared transmission spectrum, capable of detecting and scrutinising atmospheric constituents. We have included the Spitzer transit photometry of Cowan et al. (2012) as re-evaluated with the M-dwarf dilution correction by Crossfield et al (2016)
Stevenson et al. 2014 spec Hubble Space Telescope satelliteWide Field Camera 329STEVENSON ET AL 2014. HST observed WASP-12b in staring mode (not spatial scan) during its primary transit on 2011 April 12 . The WFC3 instrument utilized its G141 GRISM to acquire spectra from 1.1 to 1.7 microns over five HST orbits.
Stevenson et al. 2014 phot Spitzer Space Telescope satelliteInfrared Array Camera (IRAC)2STEVENSON ET AL. IRAC observed WASP-12b over its entire orbit at 3.6 and 4.5 microns on 2010 November 17-18 and December 11-12, respectively
