SummaryEdit

Media data and Non-free use rationale
Description Example output from the CALIB program, hosted at Queens University in Belfast. This shows probabilistic calculation of calendar ages from a given radiocarbon age range with a normal distribution, using the INTCAL13 calibration curve.

Use in article (WP:NFCC#7) Calibration of radiocarbon dates
Purpose of use in article (WP:NFCC#8) The CALIB program generates probabilistic calendar age ranges for a given range of input radiocarbon dates. The image is of an example run. This is needed to illustrate the explanation of probabilistic calendar age calculations.
Not replaceable with
free media because
(WP:NFCC#1)
These images can't be generated by an individual; to produce them a computer program such as CALIB has to be run. Any such output image would not be any more free than this image.
Minimal use (WP:NFCC#3) There will only be one image, large enough for the details to be clear. It won't be needed in other articles, though it might eventually be moved to a subarticle if calibration warrants a separate article. The resolution is not relevant because there are no additional details to be seen at higher resolution; it is inherently a low-res image.
Respect for
commercial opportunities
(WP:NFCC#2)
CALIB is not a commercial organization. In addition, the existence of an image of sample output could not be used to reduce any opportunity for use of CALIB.
