Abstract

fetched live from OpenAlex

With recent advances in large-scale space telescope missions, new sensors and technologies are made available for use in space for the first time. With the recent developments for the Coronagraph Instrument (CGI) instrument of the Nancy Grace Roman Space Telescope (NGRST), Electron Multiplying CCD (EMCCD) readout electronics and sensors are being qualified for extended use in space. To make this new remote sensing technology available for a wider range of missions, a new space camera version has been developed, with the first units outfitted with the Teledyne-e2v CCD201-20 EMCCD sensor. This novel camera, equipped with proprietary Camera Proximity Electronics (CPE), is built with a balance of space-qualified components and commercial off the shelf components with flight heritage to optimize cost, performance, and reliability. In addition to direct imaging and characterization of exoplanets, the sensitivity of this camera is also enabling Space Situational Awareness applications. The first imaging, random vibration and TVAC testing results of this new 1U camera platform named nüSpace will be presented.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
