Three on-board calibrators (a solar diffuser combined with a solar diffuser stability monitor, a spectral radiometric calibration assembly, and a black body) provide in-flight calibration.

In both cases, an independent technique is required to provide calibration of the continuous Q analysis, as arterial PP analysis cannot account for unmeasured variables such as the changing compliance of the vascular bed.

In-situ data are indispensable; they are assimilated into forecasting models, provide calibration and validation of space-based information, and contribute to analysis or filling gaps not available from space sources.

Digital radiography often provides built-in digital calibration and measurement tools that can be used to provide angle and distance data.

Such substitutes for the Sensor Bar illustrate the fact that a pair of non-moving lights provide continuous calibration of the direction that the Wii Remote is pointing and its physical location relative to the light sources.

The Excimer laser enables safe treatment of higher levels of myopia, and provide accurate calibration.

These programs provide updated calibration and reference files to be used in the data processing pipeline.

Whether the family originated in Oligocene or already in the Eocene (or perhaps even in the Paleocene) cannot be said until more fossil material is recovered, either to answer this question directly or to provide calibration for molecular phylogenetic studies.

In contrast, Webb will observe fewer supernova, but by observing them at higher redshift, fainter levels and further into the infrared, it will provide important calibration and confirmation of the JDEM results.
