Maunakea Spectroscopic Explorer Low Moderate Resolution Spectrograph\n Conceptual Design
Bibliographic record
Abstract
The Maunakea Spectroscopic Explorer (MSE) Project is a planned replacement\nfor the existing 3.6-m Canada France Hawaii Telescope (CFHT) into a 10-m class\ndedicated wide field highly multiplexed fibre fed spectroscopic facility. MSE\nseeks to tackle basic science questions ranging from the origin of stars and\nstellar systems, Galaxy archaeology at early times, galaxy evolution across\ncosmic time, to cosmology and the nature of dark matter and dark energy. MSE\nwill be a primary follow-up facility for many key future photometric and\nastrometric surveys, as well as a major component in the study of the\nmulti-wavelength Universe. The MSE is based on a prime focus telescope concept\nwhich illuminate 3200 fibres or more. These fibres are feeding a Low Moderate\nResolution (LMR) spectrograph and a High Resolution (HR). The LMR will provide\n2 resolution modes at R>2500 and R>5000 on a wavelength range of 360 to 950 nm\nand a resolution of R>3000 on the 950 nm to 1300 nm bandwidth. Possibly the H\nband will be also covered by a second NIR mode from ranging from 1450 to 1780\nnm. The HR will have a resolution of R>39000 on the 360 to 600 nm wavelength\nrange and R>20000 on the 600 to 900 nm bandwidth. This paper presents the LMR\ndesign after its Conceptual Design Review held in June 2017. It focuses on the\ngeneral concept, optical and mechanical design of the instrument. It describes\nthe associated preliminary expected performances especially concerning optical\nand thermal performances.\n

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.
