. Figure 1. Dependence of the geomagnetic A p-index on the total magnetic flux in dimmings and arcades ? : (a) for GMSs reliably identified with a definite solar eruption (filled symbols); (b) for all considered events including ones with probable solar source identification (open symbols). Red diamonds denote eruptions in ARs, and blue triangles denote eruptions of filaments outside ARs. The dashed lines delimit the accepted 20% deviation band.

... Калибровка снимка - это удаление из него паразитной информации, которая включает в себя: темновой шум, горячие пиксели, шум считывания (ток смещения), а также тени от пыли на матрице и оптике. Для калибровки снимка нужно подготовить снимки с паразитной, т.е. нежелательной информацией. В первую очередь нам нужно получить мастер-кадр шума считывания (ток смещения), на западе снимок шума считывания называют Bias или Offset . ... Уровень темнового шума сильно зависит от температуры матрицы. ...

Subsystems of the Galactic halo, their structures and compositions. ... It is shown that general populations of globular clusters and metal-poor field stars are components at least of three subsystems occupying different volumes in the Galaxy. ... The radial and vertical metallicity gradients in this oldest known Galactic subsystem provide evidence that the first heavy-element enrichment of the gas-dust medium took place before the clusters and field stars of this subsystem formed. ...
