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.

Sing et al. 2015 spec Hubble Space Telescope satelliteSpace Telescope Imaging Spectrograph36SING ET AL 2015 We observed two transits of WASP-31 b with the HST STIS G430L grating during 2012 June 13 and 2012 June 26,as well as one transit with the STIS G750L during 2012 July10. The G430L and G750L data sets each contain 43 spectra,which span five spacecraft orbits. The G430L grating covers the wavelength range from 2,900 to 5,700 ̊A, with a resolution R of λ/∆λ=530–1,040 (∼2 pixels; 5.5 ̊A). The G750L grating covers the wavelength range from 5,240 to 10,270 ̊A, with a R=530–1,040 (∼2 pixels; 9.8 ̊A).
Sing et al. 2015 spec Hubble Space Telescope satelliteWide Field Camera 325SING ET AL 2015 In addition to the STIS data, observations of WASP-31 b were also conducted in the infrared with Wide Field Cam-era 3 (WFC3) on the HST. Observations began on 2012 May 13 at 12:53 using the IR G141 grism in forward spatial scan mode over 5 HST orbits.
Sing et al. 2015 phot Spitzer Space Telescope satelliteInfrared Array Camera (IRAC)2SING ET AL 2015 We analyse two transit observations obtained using the IRAC instrument (Programme 90092 with P.I. Desert) on the Spitzer space telescope in the 3.6 μm and 4.5 μm channels in subarray mode (32×32 pixel, or 39×39 centred on the planets host). The 3.6 μm observation was performed on UT 2013 March 9 (between 06:59 and 11:37) and the 4.5 observation was performed on UT 2013 March 19 (between 12:19 and 16:58), each transit containing 8320 images
