Abstract
A new faint and large shell-type radio Supernova Remnant (SNR) G108.2-0.6 has been discovered in the Canadian Galactic Plane Survey (CGPS). The SNR shows an elliptical shell-type structure at 1420 MHz, and has a 408–1420 MHz TT-plot spectral index of α= -0.5±0.1 (ν), typical of a shell-type SNR. The remnant's flux density at 1420 MHz is 6.6±0.7 Jy, and at 408 MHz is 11.5±1.2 Jy. Both of these are corrected for compact sources. An integrated spectral index of -0.45±0.13 is determined. This new SNR has among the lowest surface brightness of any known remnants ( = 2.410-22 W m-2 Hz-1 sr-1). 21 cm Stokes Q and U CGPS data (plus preliminary Effelsberg Q and U maps) show some suggestive features that correlate with total power. observations show structures associated with G108.2-0.6 in the radial velocity range -53 to -58 km s-1, and indicate it is located in the Perseus arm shock at a distance of 3.2±0.6 kpc. At this distance the diameter of G108.2-0.6 is 58 pc. IRAS maps (12, 25, 60 and 100 μm) of the new SNR show rich infrared emission surrounding G108.2-0.6.

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.
