... From the uvby photometry and proper motions for about 5500 nearby F stars we have found the following: (i) F stars , taken in narrow ranges of metallicity , show at [fe/H] 0 rather distinct cut-off in their distribution along the Main Sequence (MS) at the blue side, which is suggested to be an indication for the MS turn-off in stellar groups of fixed metallicity ; (ii) the corresponding turn-off age from theoretical isohrones strongly correlates with the ...

... Representing Coordinate Systems (Frames) While Mappings represent the relationships between coordinate systems, the coordinate systems themselves are represented by objects called Frames. ... A Plot's base Frame corresponds with the native coordinates of the underlying graphics system. Plotting operations are specified, using AST Plot methods, in physical coordinates which correspond with the Plot's current Frame (typically this might be a celestial coordinate system). ...
