Abstract
CHIME is a radio telescope hosted by the Dominion Radio Astrophysical Observatory (DRAO) in British Columbia, Canada. CHIME operates across a wide bandwidth of 400-800MHz and has a collecting area (~80x100m^2^) and point-source sensitivity comparable to that of other 100-m class radio telescopes. The reflecting surface of CHIME consists of four parabolic cylinders. It is a transit telescope with no moving parts. For the CHIME/Pulsar project, we combine the signals from the 1024 dual polarization feeds and form 10 tied-array beams that are available as raw voltages (Ng 2018IAUS..337..179N). This means that we can track 10 different pulsars at any given time as they transit through CHIME's field of view, along the meridian. This provides very high-cadence scheduling: while many of the Northern hemisphere pulsars are being monitored daily, the longest cadence to cycle through all sources in the northern sky is only ~10d. This is reflected in the long co-added integration length of our data (Total_fold_) and the high signal to noise (S/N) achieved as listed in Table A1. The transit time of each source is a function of the declination; transit times can range from tens of minutes to hours for circumpolar sources. CHIME can in principle observe down to a declination of -20{deg}.

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
