Upgraded GMOS-N science detectors: schedule and commissioning plans
Bibliographic record
Abstract
We present plans for the commissioning of the new GMOS-N red-sensitive science detectors, currently being integrated into a new focal plane assembly at the NRC HIA. These Hamamatsu CCDs provide significantly higher quantum efficiency than the existing detectors at red optical wavelengths (longward of ~ 700 nm), with > 80% QE at 900 nm falling to ~10% QE at 1.05 μm. This upgrade not only improves current operations with GMOS-N, but also opens new spectral ranges and potential observing modes (eg. use with Altair, the Gemini-N AO module). Care has been taken to ensure that Nod & Shuffle will still be supported, since accurate sky subtraction is increasingly important at longer wavelengths due to the increased density of sky lines. The commissioning plan aims to demonstrate the improvement in current modes while minimizing the period of GMOS-N downtime for science use. The science commissioning is currently scheduled for mid-November 2010.

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.
