For 4.2 hours on September 14, 2010, Euler observed WASP-44 in search of a slight dimming in brightness until a more precise light curve could be found.
The slight difference between brightness values determined at low and high light intensities may be attributed to the increased population of unidentified dark states at higher intensities.
The satellite detects possible planets by measuring the light of 156,000 stars in its field of view and looking for slight dips in brightness when a planet crosses in front of a star.
The rectangular region was then copied, individual layers were composited using layer masks, adjusted with the Layers function, and then merged; the slight variation in brightness across the background is due to slight differences across the five original images.
Images were transferred to Adobe Photoshop CS3 for slight contrast and brightness adjustments.
Slight adjustments of brightness and contrast were applied equally to images of both, control and mutant, where applicable, and are explicitly stated in corresponding figure legend.
I did notice a very slight improvement in screen brightness on the new model, which could point to a different screen provider.
Barnard's Star has lost a great deal of rotational energy, and the periodic slight changes in its brightness indicate that it rotates just once in 130 days (the Sun rotates in 25).
They monitored more than 34,000 stars, searching for slight dips in their brightnesses from the shadows of giant planets crossing in front.
Its changes in brightness are too slight to be detected with the unaided eye.
