2020-4-5 Spectral settings. GRAVITY operates in the K-band and is offered in three different spectral setting, viz. low resolution (R~20), medium resolution (R~500) and high resolution (R~4000). The low resolution mode is only offered in dual field mode, because the dispersed fringe-tracker data also have a resolution of approximately 20 and are delivered to the user together with the science data.

2021-6-15 Gravity concentration is the separation of minerals based on differences in specific gravity. A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses. The resurgence of gravity concentration in mining has come about due to its simplicity and low environmental impact.
