... magnitude of an object is given by m = -2.5 log[Flux/F0] where "log" is the common ... magnitude that is independent of the distance of a star and only depends on the ... The relation between the absolute magnitude M , the apparent magnitude m and the ...
... Because approximate magnitudes are more useful when qualified by a terse description of their nature, the column labelled MAG should contain a character string rather than a number. ...
