. A distribution list is very useful where a group of users need to communicate amongst themselves on a regular basis. Each list is given a name just like any other user. By addressing a message to the list name, the sender can be sure that everyone will receive a copy. You cannot set up a distribution list yourself. Ask your system administrator to set one up for you.

The transparency is made by overlaying a SeaWifs image on top of an Envisat ASAR image . It reveals both the sea surface signatures of oceanic internal waves, and the surface chlorophyll concentration distribution off Portugal's west coast. It can be seen that stronger gradients of chlorophyll concentration are coincident with the oceanic internal waves' distribution. ...

To construct two-dimension distribution of minor planets user should specify elements/ parameters/ function that will be plotted as abscissas and ordinates. In three-dimension case one should add to them the element plotted on Z axis. ... Though you may choose elements plotted along different axes at will, often there is good reason to plot such elements as a, n, or n" along X axis (two-dimension distributions) and to plot them along Y axis in three-dimension case. ...
