BLAST—a balloon-borne large aperture submillimeter telescope
Bibliographic record
Abstract
The Balloon-borne Large Aperture Sub-millimeter Telescope (BLAST) incorporates a two meter primary mirror with large-format bolometer arrays consisting of 149, 88, and 43 elements operating at 250, 350 and 500 μm, respectively. The combination of the dramatically increased atmospheric transmission at balloon altitudes and the extended observing time (10–20 days) afforded by a long duration balloon flight will enable the first sensitive, large-area (≫10 deg2) sub-mm surveys at these wavelengths. These surveys will address some of the most important galactic and cosmological questions regarding the formation and evolution of stars, galaxies, and clusters as well as the source(s) of the cosmic infrared background. The BLAST focal plane will consist of arrays of silicon nitride micromesh, “spider-web” bolometric detectors operating at 300 mK coupled to 2 fλ feedhorn arrays. The first overnight test flight of BLAST is scheduled for autumn of 2002, and the first long duration balloon flight is scheduled to be from McMurdo, Antarctica in 2003–2004.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
