Parkes observations for project P875 semester 2014APRS
Bibliographic record
Abstract
In this proposal we aim to measure the flux densities of more than 500 pulsars in a systematic way. Doing this we will vastly improve upon the current spectral knowledge of the pulsar population and provide at least 1000 new measurements at 732 and 3100 MHz for about a quarter of the currently known pulsars. This is extremely important both for pulsar population studies, in particular for determining the spectral index of the radio emission, investigations of the pulsar emission mechanism and for optimizing observing strategies for next generation telescopes, such as the SKA. This proposal also acts as preparatory work for the Molonglo Observatory Synthesis Telescope, which we are refurbishing at the moment. This work will help us constrain the flux density expected at the centre frequency of Molonglo, at 843 MHz. We will also use the new data from Parkes to check and update the ephemerides of all the selected pulsars in order to have a database that is as up to date as possible before observations with Molonglo commence. We will also investigate the averaged pulse profiles and how they change with frequency.
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.

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.
