The quad-mirror optical telescope concept for the Maunakea Spectroscopic Explorer
Bibliographic record
Abstract
A quad-mirror (QM) telescope optical concept has been designed for the Maunakea Spectroscopic Explorer (MSE) project. The goal of MSE is to repurpose the existing Canada-France-Hawai‘i Telescope (CFHT) site without changing the footprint of the observatory. This repurposing imposes numerous constraints on the telescope, including space constraints limiting the size of the telescope and the space available for the large number of spectrographs required, dimensional constraints (limits the size of any monolithic mirrors), and mass limits along with other logistical constraints that wouldn't necessarily exist for a facility designed from first principals. The QM concept offers several scientific and versatility advantages over the original prime focus baseline, but it poses some challenges, such as the size of the tertiary mirror. This design serves as input into the effort to understand how best to implement a QM design and to determine if there are any arising hard showstoppers for use in MSE. An overview of the optical design is presented with its benefits, areas of compromise to meet currently known constraints, and evaluation of preliminary optical sensitivities and metrology needs.

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.
