A KINEMATIC DISTANCE STUDY OF THE PLANETARY NEBULAE-SUPERNOVA REMNANT-H II REGION COMPLEX AT G35.6–0.5
Bibliographic record
Abstract
Two possible planetary nebulae (PN G035.5−00.4 and IRAS 18551+0159), one newly re-identified supernova remnant (SNR G35.6−0.4), and one H ii region (G35.6−0.5) form a line-of-sight-overlapping complex known as G35.6−0.5. We analyze 21 cm H i absorption spectra toward the complex to constrain the kinematic distances of these objects. PN G035.5−00.4 has a distance from 3.8 ± 0.4 kpc to 5.4 ± 0.7 kpc. IRAS 18551+0159 is at 4.3 ± 0.5 kpc. We discuss the distance for SNR 35.6−0.4, for which the previous estimate was 10.5 kpc, and find a plausible distance of 3.6 ± 0.4 kpc. The new distance of SNR G35.6−0.4 and the derived mass for the ∼55 km s −1 CO molecular cloud can accommodate an association with HESS J1858+020. We also conclude that SNR G35.6−0.4 is unlikely to be associated with PSR J1857+0210 or PSR J1857+0212, which are projected onto the SNR area.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
