[SPOTS]

[Spots Primary]

       The total number of spots on each star is
       a compile-time configuration option (the default
       is ten). 
       However, only <two> spots per star can be defined
       interactively. Each of these two spots can be 
       <switched on/off> seperately.
       (If you want more spots, you have to define
       them on the command line or in a configuration
       file.)

       For the <definition> of a spot, the following
       four parameters are required:

	    <Longitude> in degrees, counted clockwise from the 
	    line pointing from the <Primary> to the <Secondary>

	    <Latitude> in degrees, counted from the equator

	    <Radius> in degrees

	    <Dimfactor> is the (dimensionless) factor, by
	    which the temperature in the spot region is higher
	    or lower than the stellar surface temperature.
	    <Note:> actual <brightness> is proprtional to the
	    fourth power of the temperature !
