cds-question@unistra.frmultiple-starssolar-system-planetsphotometryoccultationQatar-1b is a close-orbiting hot Jupiter (Rp~=1.18R_J_, Mp~=1.33M_J_) around a metal-rich K-dwarf, with orbital separation and period of 0.023AU and 1.42-days. We have observed the secondary eclipse of this exoplanet in the Ks band with the objective of deriving a brightness temperature for the planet and providing further constraints to the orbital configuration of the system. We obtained near-infrared photometric data from the ground by using the OMEGA2000 instrument at the 3.5m telescope at Calar Alto (Spain) in staring mode, with the telescope defocused. We have used principal component analysis (PCA) to identify correlated systematic trends in the data. A Markov chain Monte Carlo analysis was performed to model the correlated systematics and fit for the secondary eclipse of Qatar-1b using a previously developed occultation model. We adopted the prayer bead method to assess the effect of red noise on the derived parameters.2016A&A...595A..61Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/595/A61CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/554/A28 : Qatar-1 differential light curve (Covino+, 2013)J/A+A/555/A92 : Transit timing variations on Qatar-1 (von Essen+, 2013)J/A+A/577/A109 : Transit times of Qatar-1b (Maciejewski+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/595/A61https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/595/A61http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/595/A61https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/595/A61https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/595/A61http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/595/A61GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/595/A61/fig3_lcDetrended light curve with the secondary eclipse of Qatar-1b in the Ks band as a function of the orbital phaserecnoRecord number assigned by the VizieR team.
