Abstract

fetched live from OpenAlex

Within the open cluster project BOCCE, we present a preliminary analysis of three low latitude fields imaged with the Canada-France-Hawaii telescope (CFHT), with the aim of better understanding the Galactic structure in those directions. Thanks to the deep and accurate photometry, these wide fields represent a unique and severe benchmark for galactic models. In the present paper we discuss if a canonical star count model, expressed in terms of thin and thick disk radial scales, thick disk normalization and reddening distribution, can explain the observed CMDs. The goodness of fit is evaluated with a KolmogorovSmirnov test. The classical decomposition halo/thin/thick disk seems able to reproduce the observations without additional structures.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
