Abstract
The BRITE-Constellation is a group of Canadian/Austrian nanosatellites that will examine the apparently brightest stars in the sky for variability using precise differential photometry. The constellation consists of four low Earth-orbiting nanosatellites, divided into pairs, with each member of a pair having a different optical filter. Each BRITE satellite will observe a region of interest for up to 100 days or longer, allowing measurement of stellar variability on the order of hours to months. Each BRITE satellite utilizes a number of new, innovative technologies including reaction wheels, star tracker and optical telescope, all sized and designed around Space Flight Laboratory’s 5-kilogram, 20x20x20 cm CanX nanosatellite bus. The BRITE science instrument is a low power CMOS detector coupled with a lens system designed to provide a telecentric, slightly defocused image optimized for observing stellar intensity with an accuracy of 1 mmag per data point per orbit down to a visual magnitude of +3.5. Photometric measurements will have an error amplitude spectrum no greater than 20 ppm over measurement periods longer than a month. The optics will have a small (30 mm) aperture and a maximum length of 100 mm in order to fit within the nanosatellite bus.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
