Abstract
The Cosmological Advanced Survey Telescope for optical and UV research (CASTOR) is a proposed Canadian Space Agency-led mission that will provide wide-field imaging and spectroscopy in the ultraviolet and blue optical region. CASTOR will fill the “UV-optical gap” in space astronomy after the Hubble Space Telescope, enabling new discovery opportunities in the solar system and beyond to the nature of the cosmos, especially in partnership with the other great wide-field observatories of the next decade (e.g., Euclid, Roman, Rubin). Here, we expand on FORECASTOR (finding optics requirements and exposure times for CASTOR), a coordinated suite of science planning tools for the CASTOR mission. We describe a pixel-based, user-friendly, exposure time calculator for the UVMOS spectroscopic mode, complementary to the photometric exposure time calculator developed earlier this year. These open-source tools are hosted on the Canadian advanced network for astronomical research for community use with no configuration required.

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
