The phrase "extraction areas" is grammatically correct and can be used in written English.
It is typically used in the context of mining or other sources of extraction such as oil or gas. For example, "The environmental regulations need to be more strictly enforced in the extraction areas."
According to national strategies for extracting peat in Finland, new peat extraction areas should be established on previously drained peatlands.
In addition, many of the early developments are being decommissioned, specifically military and natural resource extraction areas.
c, XMM-Newton 1.5 2.6 keV emission map in greyscale, showing the extraction areas of the Chandra spectra used to derive the latitudinal profiles at l = 0°, with colours corresponding to those of the spectra.
We define the full model expression to include the source and background components, including the scaling of the background to account for the different spectral extraction areas of the source and background.
Maintenance-free RF sources for negative hydrogen ions with moderate extraction areas (100 200 cm2) have been successfully developed in the last years at IPP Garching in the test facilities BATMAN and MANITU.
The ITER neutral beam system is using inductively coupled radio frequency (RF) ion sources, that have demonstrated the required ITER parameters on (small) sources with extraction areas up to 200 cm200
Combining background spectra with wildly varying spectral extraction region areas may yield misleading uncertainty estimates; i.e., some extractions will be over-represented while others will be under-represented.
Rather than basing the variability estimate on the extracted counts per good time in a time bin, glvary uses the extracted counts per good time in a bin per normalized extraction area.
Through a four electrode grids system inside the accelerator, a negative ion beam will be extracted and accelerated up to −60 kV on a reduced scale extraction area of 12 × 50 cm2 (the area of PG apertures is 185 cm2).
Fig. 4.10 shows the ratio of diffuse spectra extracted from annuli centered on the specular image of Her X-1 (normalized by extraction region area) to the corresponding spectrum extracted from the ACIS transfer streak for the source; the transfer streak spectrum is thought to be ∼ 4% piled up. Figure 4.10: Hardening of the diffuse mirror scattering halo with distance from the direct image.
The backscale, read from the BACKSCAL header keyword, is the ratio of data extraction area to total detector area.
