Abstract

fetched live from OpenAlex

Developing new instruments and upgrading existing instruments has been an important aspect of Subaru telescope's operation. Seven facility instruments and two visiting instruments are currently under use. Among them HiCIAO, a coronagraphic imager combined with adaptive optics (AO188), has started its full operation in the 2nd semester of 2009. We are using HiCIAO for a large program (SEEDS) to find new exo-planets and comprehend planet formation from proto-planetary disks. To achieve higher contrast, a new coronagraph attachment with an extreme AO (SCExAO) will be installed as a PI instrument. AO188 is also used with the IRCS in natural guide star mode. Its laser guide star mode is currently commissioning. The Fibre multi-object spectrograph (FMOS), which is comprised of 400 fibers placed at the prime focus and delivers 0.9-1.8um spectra, will be partly offered to open use from mid 2010. Hyper Suprime-Cam, the wide-field upgrade (1.5 deg FoV) of the Suprime-Cam, is under development for its first light in 2011. Development of an immersion grating has taken place for upgrading the IRCS with a high-resolution infrared spectrograph.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
