radio astronomy
Enable an AI agent to recognise radio astronomy activities, assess whether their observations support the intended scientific use, and determine justified next actions.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise radio astronomy activities, assess whether their observations support the intended scientific use, and determine justified next actions.
Radio astronomy is the observational science that studies celestial objects and the interstellar/intergalactic medium by collecting and analysing naturally emitted electromagnetic radiation at radio wavelengths (typically ~10 MHz to ~1 THz), using antennas, interferometers, and spectrometers rather than optical telescopes.
It can be Translate a scientific objective into required frequency, angular, temporal and polarization coverage.; Select observations whose configuration and quality fit a stated analysis.; Identify interference, missing calibration or sampling limitations that require correction or restrict use.; Produce or request calibrated images, spectra, time series or polarization products with traceable processing.; Assess detections, non-detections and competing interpretations against measurement uncertainty.; Recommend reprocessing, independent verification or follow-up observations within recorded access and scheduling constraints..
Distinguishing features
The activity measures or analyses radio signals associated with astronomical sources or sky emission; operating radio equipment alone does not qualify.
Its intended result concerns an astronomical property or phenomenon, rather than delivery of a communications message.
Its evidence depends on a radio measurement response, such as an antenna beam, receiver bandpass or interferometric sampling pattern.
It distinguishes candidate astronomical signals from instrumental effects and terrestrial interference before treating them as scientific evidence.
It can operate on archived observations without owning or operating a telescope, provided the radio measurement provenance remains available.

Characteristics
- Scientific objective
- Continuum, spectral-line, timing, transient, polarimetric or combined investigation Determines which observables, configurations and validation checks are necessary.
- Target and sky coverage
- Named sources or sky regions, with coordinate frame, epoch and coverage footprint Establishes what was observed and whether coverage supports the intended claim.
- Frequency coverage
- Hz, including channel widths, gaps and frequency reference frame Controls which emission features can be measured and whether observations can be compared.
- Angular response
- Beam dimensions in arcseconds or radians, with response description and recoverable angular-scale limits where applicable Determines source separation, spatial interpretation and possible loss of extended emission.
- Temporal sampling
- Seconds for integration and cadence; timestamps with a declared time standard Determines whether variability, pulses or short events can be resolved and aligned.
- Measurement sensitivity
- Noise or uncertainty in Jy, K or another declared observable unit, at stated bandwidth and integration Supports detection assessment and meaningful upper limits.
- Polarization products
- Recorded correlations or Stokes parameters, with basis and sign conventions Identifies which polarization claims are supportable and which corrections are required.
- Calibration readiness
- Unassessed, incomplete, applied, validated or failed, separately for each required correction Prevents an overall readiness label from hiding a missing correction.
- Interference impact
- Flagged fraction and residual contamination assessment by frequency, time and relevant signal product Shows which measurements remain usable and where contamination may imitate a source.
- Evidence lineage
- Links among observations, calibration inputs, processing versions, derived products and scientific claims Allows an agent to trace, reproduce or challenge a result.

Scientific intent and targets Connects the astronomical question to the radio evidence needed to answer it.
An observation can be technically successful while failing to measure what the investigation requires.
Radio observables
Records the measured quantities and their intended scientific role.
Objective-to-observable fit
Records whether the requested radio measurements can discriminate among the proposed astronomical explanations.
- Which astronomical question is being tested, and which radio observable would constrain its answer? definition
- What frequency, sensitivity, angular, temporal or polarization requirements must be met for that test? measurement
Target selection and coverage
Records the intended source population or sky region and the actual observational coverage.
Selection and pointing basis
Preserves target selection, coordinate conventions and coverage gaps that affect interpretation.
- How were targets or survey fields selected, and which catalogue, coordinate frame and epoch define their positions? provenance
- Which sources, sky regions or observing intervals fall outside the achieved coverage or selection criteria? boundary
Radio measurement configuration Describes how reception and sampling transform sky emission into recorded measurements.
Instrument response determines what structures and signal variations can be recovered.
Reception and sampling
Records receiver coverage and the spectral, temporal and polarization products actually retained.
Recorded signal capability
Identifies whether the retained measurements contain the information required for the intended analysis.
- What frequencies, channel widths, integration times and polarization products were recorded, using which conventions? measurement
- Which desired signal features are unresolved, outside the band or irreversibly lost through averaging or product selection? boundary
Spatial response
Captures beam response, scanning or array sampling and their consequences for sky reconstruction.
Recoverable sky structure
Records the spatial scales and regions for which the observation provides defensible information.
- What beam, scan pattern or baseline sampling defines the angular response and field sensitivity? measurement
- Could blending, sidelobes or insufficient sampling of large angular scales alter the apparent source structure or flux? boundary
Signal integrity and calibration Tracks contamination and the corrections needed to relate recorded signals to astronomical quantities.
Radio detections and measured properties require evidence that interference and instrumental response have been adequately addressed.
Interference discrimination
Records evidence used to distinguish astronomical emission from unwanted radio signals and instrumental artifacts.
Contamination and flagging evidence
Preserves interference assessments, rejected samples and the possibility that rejection removed astronomical signal.

Correction chain and residuals
Connects calibrated measurements to their reference inputs, validity intervals and remaining systematic errors.
- Which flux, gain, bandpass, polarization or propagation corrections are required, and what reference observations or models support them? provenance

An agent must distinguish a measured feature from its physical explanation and choose actions that resolve remaining uncertainty.
