The triangulation, using observations, interviews and documentation, was useful in establishing confidence in the truth of the data.
Using observations from the ground, scientists had already observed that Comet 67P, like many other small bodies in our Solar System, appeared to be grey "on average".
Checking Dr. Spence's calculations, Dennis Rawlins and Keith Pickering almost immediately recognized a mistake in using observations of the two stars to establish true north at Giza.
The researchers were able to estimate the amount of water lost using observations made by the Very Large Telescope at the European Southern Observatory.
We directly estimated the density of C pools after fire, using observations from CSE plots.
This paper also includes calibration of the IMEUM output using observations from ground sensors.
The problem of tracking multiple sources using observations acquired at spatially scattered sensors is considered here.
The model has been tested successfully using observations from a monitored green roof in Florida.
Key processes were parameterized for the improved ACASA model using observations.
The spacecraft charge can sometimes be estimated using observations of photoelectron peaks of known energy, e.g. Franz et al. (2006).
In the first method, using observations on the common support, we stratified the observations based on the propensity score.
