Aperture photometry of Spitzer space telescope observations of HD209458 b in the 3.6µm channel was conducted. Tond deviations in the exoplanetary infrared emission, the modelling of secondary eclipse light curves was carried out. Thenoise from intrapixel sensitivity variations was modelled by Gaussian processes. The obtained value of the eclipse depth is0.094±0.013% of the total ux of the system and is consistent with the results of previous work and the works of otherauthors.
