Creating a custom region will avoid background contamination by either of the sources.
Seasonality is the main factor accounting for biomarkers variability, and not background contamination level.
We incorporate spectral models, background contamination, and a latent Poisson process for the number and positions of the sources.
We further incorporate spectral models, background contamination, and a latent Poisson process for the number and positions of the sources.
Such a method is instrumental in separating the primary impact-generated flexural waves from severe background contamination.
Source of background contamination was also discussed based on the analysis of various amounts of standard materials.
The difficulty can be overcome to some degree by achieving lower background contamination, by improving instrument sensitivity, and by finding minerals with abundant parent isotopes.
In practice, however, inferring properties of source populations from observational data is complicated by detector-induced uncertainties, background contamination and missing data.
This includes background contamination, uncertainty on both intensity and location of sources, and, most challenging, the issue of non-detections or unobserved sources.
HRC-I gain maps are used for hardness ratio or PI spectral analysis studies, and useful for reducing the background contamination for extended sources and weak point sources.
As noted earlier, this in turn was possible solely because the lead background contamination had been reduced from 1 × 10−6 gram to almost 1 × 10−12 gram per analysis.
