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.

Hoyer et al. 2013 phot 4.1m Southern Astrophysical Research (SOAR) Telescope at Cerro PachonSOI3HOYER ET AL 2013 We have observed a total of 12 transits of WASP-4b, between August 2008 and September 20112.Three transits were observed with the SOI at the SOAR telescope and the remaining nine were observed with the Y4KCAM at the 1-m CTIO telescope. The first ten transits were observed using a Bessell I or Cousins I filter. For the 2011 transit observations we use the 4x4 binning mode of the Y4KCam and a Cousins R filter.The observing log is summarized in Table 1 https://arxiv.org/pdf/1306.0489.pdf

Huitson et al. 2017 phot Association of Universities for Research in Astronomy (AURA) 8.1m Gemini South Telescope at Cerro PachonGMOS4HUITSON We observed four transits of WASP-4b in the optical at low resolution, using the Gemini South telescope located at Cerro Pachon, Chile. The observations were similar to the multi-object spectroscopy observations pioneered by Bean et al. and widely used. For each observation, we used the MOS mode of GMOS to observe time-series spectrophotometry of WASP-4 and a similar magnitude comparison star simultaneously. We observed one transit of WASP-4b using the B600 grating, covering a wavelength range of 400-650 nm with ideal resolving powerR= 1688. This transit was a pi-lot study to assess whether Gemini GMOS was suitable for a survey of exoplanet transmission spectra. We then began our survey of hot Jupiter atmospheres, in which we observed a further three transits of WASP-4b using the R150 grating. The R150 grating covers a wavelength range of 525-900 nm with ideal resolving power R= 631.Note that the ideal resolving powers for both gratings assume a slit width of 0.5 arcsec.
