... In some of the shots the Sun creeps into view - particularaly during the sunset sequence. ... The dust halo takes up a lot of rendering time so it is usually deactivated - it would be nice to have it enabled during the final descent and impact but the number of light sources required would make this unfeasably slow. ... There are two orbiting cameras in different planes - one to show the earth and the other to show the sun being eclipsed by the asteroid. ... Last sunset for the asteroid . ...

... AstroCC is a coordinate conversion utility for astronomy. It accepts an object designation or the coordinates of an object and calculates coordinates in alternative systems, and at different dates, times, and locations. It also provides lunar and bright planet coordinates to aid in planning observations. ...

Suppose we have 3 point-like masses (m 1 , m 2 , m 3 ) orbiting under their mutual attraction. The three form a triangle ABC with sides masses (R 1 , R 2 , R 3 ) where R 1 is the side across from m 1 , R 2 is across from m 2 and R 3 is across from m 3 (Figure 1). ...

... The parameter pgdev allows the user to specify a pgplot device, but, in contrast to the pgplot standard, the file name should not be included, but instead supplied via the parameter plotfile . ... To write a colour postscript file called op.ps: pgdev=/cps plotfile=op.ps . However note that at present, if a colour postscript device ( pgdev = `/cps'), a fits file ( pgdev = `/fits') or a ppm file ( pgdev = `/ppm') are selected, the task in fact bypasses pgplot and writes the postscript file directly. ...
