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.

Demory et al. 2011 phot Spitzer Space Telescope satelliteInfrared Array Camera (IRAC)155 Cnc was observed by Spitzer on 6 January 2011 from 9h41 to 14h39 UT. The data consist of 5240 sets of 64 individual subarray images obtained by the IRAC detectorat 4.5 microns with an integration time of 0.01s, and calibratedby the Spitzer pipeline version S18.18.0. They are available on the Spitzer Heritage Archive
Demory et al. 2016 phot Spitzer Space Telescope satelliteInfrared Array Camera (IRAC)6DEMORY ET AL : This study is based on six transits and eight occultations of the super-Earth 55 Cnc e acquired between 2011 and 2013 in the 4.5-μm channel of the Spitzer Space Telescope (Werner et al. 2004) Infrared Array Camera (IRAC) (Fazio et al. 2004). Data were ob-tained as part of the programs IDs 60027, 80231 and 90208. Two transits were observed in 2011 (PID 60027) (Demory et al.2011;Gillon et al. 2012), four occultations in 2012 (PID 80231)(Demory et al. 2012), as well as four transits and four other occultations in 2013 (PID 90208). The corresponding data can be accessed using the Spitzer Heritage Archive1. All Spitzer observations have been obtained with the same exposure time (0.02s) and observing strategy (stare mode). The last three occultations of PID 80231 have been obtained using the PCRS peak-up mode asall of our 2013 data. The PCRS peak-up procedure is designed to place the target on a precise location on the detector to mitigate the intra-pixel sensitivity (Ingalls et al. 2012, and references there in).The AORs 48072704 and 48072960 experienced 30-min long interruptions that happened during the ingress and egress of 55 Cnc e's transit respectively.
de Mooij et al. 2014 spec Nordic Optical TelescopeALFOSC8ALFOSC DATA : Both stars were observed simultaneously in differential spectrophotometry mode with the #7 grism, which provides a wavelength coverage from 3800 ̊A to 6800 ̊A.
Tsiaras et al. 2016 spec Hubble Space Telescope satelliteWide Field Camera 325TSIARAS ET AL 2016 : We downloaded the publicly available spectroscopic images of the transiting exoplanet 55 Cancri e (ID:13665) from the MAST Archive. The dataset, obtained with the G141 grism, contains two visits of four HST orbits each.
