Abstract
Abstract Empirical transformations of selected broadband filters in the Hubble Space Telescope Wide Field Camera 3 (WFC3)/UVIS camera into the BVI system are derived. These conversions employ photometry of stars in a standard field in the globular cluster 47 Tucanae that has repeatedly been imaged with both the WFC3 and Advanced Camera for Surveys (ACS) cameras, enabling direct comparisons of photometry for large numbers of stars over a wide range of colors. The photometry of these stars on the ACS camera is used to define their BVI magnitudes, through the standard transformations from Sirianni et al. These BVI magnitudes are then used to define the conversions from the native WFC3 filter system. Results are presented for six WFC3 broadband filters: F 438 W , F 475 W , F 475 X , F 555 W , F 606 W , F 814 W . For these, convenient equations are given to transform ( F 438 W , F 475 W , F 475 X ) into standard B , ( F 555 W , F 606 W ) into V , and F 814 W into I . In a parallel study with the same database, a new transformation is presented for conversion of the ACS/WFC F 475 W filter into B .

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; a candidate call from one teacher head, not a consensus.
