Copy labels and units from the source; leave unknown fields unknown.
Separate what was measured from what a model infers.

1. IDENTIFY THE RELEASE
Release title and official URL:
Publication date:
Observation date(s), if applicable:
Mission stage: commissioning / science operations / other:
Material: simulation / ground test / sky observation / analysis:
Instrument: WFI / Coronagraph / other observatory:
Survey or observing program:
Paper URL and version/date:
Publication status: preprint / peer-reviewed / revised:

2. PRESERVE THE DATA CONTEXT
Archive or dataset URL:
Dataset release identifier and product type:
Calibration/pipeline version and reference context, if supplied:
Filters or spectral band, with units:
Field area, depth and exposure:
Cadence and monitoring duration for time-series work:
Image scale, orientation and assigned colors:
Quality flags, masks, missing coverage or overlapping sources:
If simulated: input population, truth catalog and simulation version:

3. FOLLOW THE EVIDENCE
Measured signal (brightness / redshift / shape / light curve / other):
Numerical value, units and uncertainty:
Interpretation supported by that measurement:
Model and assumptions used:
Alternative explanations tested:
Comparison sample or model:
Selection rule and detection efficiency/completeness:
Possible false positives:
Random uncertainty versus shared systematic uncertainty:
Independent measurement or follow-up available:

4. WRITE THREE SENTENCES
The team measured:
This supports:
The next useful check is:

5. REVISIT
New release/paper URL and date:
Did calibration, sample definition or observing coverage change?
Did new observations change the interpretation?
Updated three-sentence note:

WORKED EXAMPLE — INVENTED, NOT ROMAN RESULTS
1,000 representative artificial sources inserted; 800 recovered.
Efficiency = 800 / 1,000 = 0.80 (80%).
100 genuine detections in the same defined real population and conditions.
Simplified completeness-adjusted estimate = 100 / 0.80 = 125.
100 remains the observed count; 125 is an inferred population estimate.
Assumptions: representative test sources, matching selection/conditions,
no false positives, and uncertainty omitted for this teaching calculation.
Real analyses must model changing efficiency and propagate uncertainty.
