... With enough velocity, a spacecraft can break loose from the Earth's gravity and enter an orbit around the Sun, like that of a planet. If it then orbits the Sun with the same period as the Earth--one year--it may keep a fixed position relative to Earth. ... If the distance is just right--about 4 times the distance to the Moon or 1/100 the distance to the Sun--the spacecraft, too, will need just one year to go around the Sun, and will keep its position between the Sun and the Earth. ...

... Posts tagged ?point pattern analysis? ... There are three distinctive subjects in spatial statistics: geostatistics , lattice data analysis , and spatial point pattern analysis. Because of the resemblance between the spatial distribution of observations in coordinates and the notion of spatially random points, spatial statistics in astronomy has leaned more toward the spatial point pattern analysis than the other subjects. ...

... A detailed study of two consecutive bright points observed simultaneously with CDS, EIT and MDI is presented. The analysis of the evolution of the photospheric magnetic features and their coronal counterpart shows that there is a linear dependence between the EIT Fe XII 195? flux and the total magnetic flux of the photospheric bipolarity. ... In a follow-up study, we used wide slit (90arcsec240arcsec) movies of four EIT coronal bright points (BPs) obtained with CDS. ...

... The keywords EXPRTIME and ZEROMAGN set the zero point for magnitudes. ... The program automatically determines a Point Spread Function when it gets proper initial values from the keywords SPROFIL. Initial values may be wrong by 0.1 each, and the program still can converge to the right Point Spread Function. ... The program looks for an initial point spread function into that descriptor at first and it uses data from the keywords SPROFILx when the descriptor DPROFILE is absent. ...
