... Review Article . ... David P. Stern, Laboratory for Extraterrestrial Physics . ... The history of geomagnetism began around the year 1000 with the discovery in China of the magnetic compass. Methodical studies of the Earth's field started in 1600 with William Gilbert's "De Magnete" and continued with the work of (among others) Halley, Coulomb, Gauss and Sabine. ... From that came modern dynamo theory, of both the solar and terrestrial magnetic fields. ... The Earth's Dynamo . ... References: A-G . ...

... This program was created for correlating chosen regions in the series of fts images. ... Chosen regions' . ... In this section the program counts the integral for each region of the grid for each image. ... As a matter of fact, the integral is total brightness of the region and it is counted by 'int_tabulated' IDL function. ... In addition, the program will show the count of the regions which correlate with the corresponding region (the brighter region means the bigger count) and its contour. ...
